The myON app is designed for offline reading, but you need to be connected to a WiFi network when logging into the app for the first time to link your account. This is to troubleshoot account linking issues.
If you are having a problem logging in using the myON App on a Chromebook, please check the following:
Verify that you have a good internet connection. As stated above, linking a user to the app requires an internet connection.
Verify that you have the latest version of the app. To check for the most updated version, check the Chrome Web Store.
Try the PIN number from your myON account. This can be attained by clicking the blue button at the top of screen when accessing myON from a web browser.
Try connecting to myON using a web browser on your Chromebook instead of the myON app. This will verify that your account is active and functioning, and that the school name, username and password information you are using is accurate.
Try uninstalling, and reinstalling the app.
