This may be because you do not have location services enabled. Your provider uses your location to authenticate your account.
For Android:
Please delete and reinstall the TBS app from the app store. When you install the TBS app from the Google Play store, you will be prompted to either disable or enable location services. Please select enable, then you should no longer experience this issue.
For iOS:
Please delete and reinstall the TBS app from the app store. When you launch the TBS app for the first time, you will be prompted to either disable or allow location services. Please select allow, then you should no longer experience this issue.
Use same login credentials:
Make sure you are using the exact same login credential and TV provider for TNT, TBS, and truTV app. If you switch between different logins and providers across the three networks, this may create an authentication error with our Single Sign On feature and allow auto login incorrectly. This may particularly happen with AT&T, Directv, and Directv Stream sharing a AT&T domain.
Please try logging out of all three apps, disconnect your wifi from your device, and restart your device.
