Issue:
The Acellus App is not downloading from the Apple App Store onto a iPhone or iPad device.

Check for an Update:

1. Go to the Settings App.
2. Click “General” and then click “About”
3. Select “Software Update”. You will then need to allow the device some time to check for an update. Once it has checked, the device will either let you know that an update is available, or give your iOS version and say “iOS is up to date.”

Note: If your device indicates it is up to date but is running iOS/iPad iOS version 16.3 or lower, it is no longer supported by Apple and cannot download the current Acellus app.

Check System Compatibility:

1. Go the Acellus App.
2. Scroll to the ‘Information’ section and locate the ‘Compatibility’ option (fourth item). If your iOS version meets the requirements, it will display ‘Works on this iPhone.’ If not, tap the arrow to view the compatibility requirements.

1. Go to the Settings app.

2. Go to “General” and select “Software Update.” Allow the device to check for updates. Once complete, it will either indicate an available update or display the macOS version with the message “macOS is up to date.”

1. Go to the Acellus App in the Apple App Store.
2. Scroll to the ‘Information’ section and locate the ‘Compatibility’ line. If your macOS version meets the requirements, it will state that it works with your device. If not, click the arrow to view the compatibility requirements.

Issue:
When signing into the student account you receive the error message, “Not Registered at This Location.”

Solution:

• This would indicate that you are using an Easy Sign-In. These sign-in credentials will only work when using the same Device/Wifi Network where they were created.
• You need to use the original 10-digit student ID along with the randomized 6-digit password that you received when signing up. You can find these in the email you received upon enrolling, or you can follow these steps: Finding a Student’s ID and Password
• Sometimes occurrences like a WiFi Router Reboot, Power Outage, or changing Internet service providers can result in your Easy Sign-In not being recognized. If this occurs, you can simply create the Easy Sign-In again.

Issue:
When signing into the student account you receive the error message, “Unknown user or incorrect password”

Solution:
This issue usually comes up when the password you are using has been mistyped. Compare the password you have with the one found in your Parent Account: Finding a Student’s ID and Password

*Password is case sensitive, and there are no spaces in the Student ID.*

Issue:
While your student is signed in you receive the error message, “Signed Out – You’ve been signed out due to inactivity.”

Solution:  This Message typically appears for one of the following reasons:

1. Multiple Logins Detected: Signing into Acellus from multiple devices simultaneously causes automatic logout. Ensure the student is signed in on only one device at a time to avoid session disruptions.

2. Session Timeout Due to Inactivity: If a student remains idle for an extended period, the session will automatically time out, requiring re-login.

3. Network or Connection Issues: Poor or unstable network connections can trigger logout errors. If this issue persists, review the “Video is Taking too Long to Play” section for troubleshooting steps.  

Issue: Videos are giving an error.

Solutions:

– Update Your Device: We recommend that you use the Acellus App. Please check the Device Requirements & Compatibility (see above) to be sure that your student’s devices are using supported software. In addition, make sure that your students are using the latest version of the Acellus App.

– The Browser’s Cache is Too Full: Browsers often cache data in order to minimize loading and buffering times. When students watch multiple videos, their browsers may cache up more data than their computers can hold and still function properly. When this happens, performance suffers, and sometimes Acellus videos will not play. To correct this, clear the browser’s cache. You can find instructions for how to do this on your browser by doing a quick search on your favorite search engine. When using the Acellus App, clear the cache on your device’s native web-browser.

– Try a Different Device: If you have already updated your device and cleared your web browser’s cache, try using a different device to login.

If issue persists; contact us.

Issue:
Repeating lesson videos that were already previously watched.

This problem is usually caused by one of two issues. Sometimes there is a Wi-Fi / Internet issue similar to those listed under “Video Error Message” or “Video is Taking too Long to Play” (see above).

However, sometimes the student reports that the video keeps starting over, when actually they are struggling with the material. When students repeatedly enter wrong answers to questions, Acellus will restart the video, or will start another video on the same topic. Students sometimes try to keep going, even through they don’t really understand the material, but they eventually become discouraged because they feel that they are caught in a never-ending loop.

To determine whether or not this is the problem, you can do the following:

1. 1. Sign into the Parent Account. (Need step-by-step instructions?)
   2. Select the student’s name -> the Course -> the last problem step done by the student.

If you see wrong answers interspersed with multiple help videos (and possibly some correct answers), then this is likely the problem.

Solution:  
Acellus provides help in addition to the extra help videos the student has already seen, including an on-screen Lesson Manual and, quite often, Problem Solving Help (short videos explaining how to do a particular kind of problem). To access these help items, in the Student Interface while looking at the problems, select the Help tab on the right side of the screen. Here you will see buttons for the Lesson Manual, Lesson Videos, and sometimes Problem Solving Help. Often, with additional help from Acellus, students can gain the understanding they need to move forward.

If issue persists; contact us.

Issue:

   3. Select “Create a Goldkey/Soft-token”
