Will not register once closed

Every time I close the app out, when I try to open it again, it bypasses the primary account and goes straight to trying to register the secondary account, but it will not register and gives a failed error. I have tried disabling the secondary account, renaming it to primary, logging completely out and logging back in, and recreating the primary account. None of these are successful.
If I leave the app running in the background it completely drains my battery within 4 hours.

The only workaround is to completely delete the app and reinstall every time I close it, which is every single day.
