Please make sure that you are using the correct app:
The app for your magazine can be found here: iPhone (Please note: the Google or Android app is being discontinued.)
The app will show up inside of the Newsstand app as the latest magazine cover or a blue icon. You can login under the settings (gear) icon as explained HERE.
We also have an app for Rivals members (BlueandGold.com) for iPhones and Android here. This app will appear as a blue Rivals logo on your device home screen, which is how you can tell that it is not the magazine app.
NOTE: The login for BlueandGold.com app requires a paid membership with Rivals. However, there are some free articles on there too, and the recruiting database, rosters and schedules are all available without a login. There are even several free message boards, if you would like to chat with fellow fans.
