Are you sharing your login with others? Some app developers will make you re-authenticate if it detects a login from a different IP address.
If the credentials are only being used at the one location, then there may be some bad data stored within the app. If that's the case:
- Remove the app
- Reboot the Roku
- Reinstall the app
Log in again and see if it retains the data.
If you have multiple Roku devices:
- Remove the app from one Roku device
- Reboot all Roku devices
- Reinstall the app on one Roku device
Log in and check each device.
Don't skip any of the steps, and don't jumble the order of the steps.
