I am experiencing a persistent mobile login issue affecting my Blizzard account across multiple Android devices.
Both the Battle.net app and Hearthstone repeatedly prompt me to log in, even after a successful authentication. Login does complete, but the session does not persist. After a short period or relaunch, I am asked to log in again.
This issue originally appeared on a new device and has since propagated to my previous device, which had never experienced this problem before.
What makes this notable:
-
Issue reproduces on multiple Android phones
-
Factory reset performed and restores skipped
-
Only Battle.net and Hearthstone installed
-
Issue now affects a device that previously worked correctly
-
Occurs on multiple networks
-
Behavior is identical across devices
This strongly suggests an account-level mobile authentication or session persistence issue, not a device, OS, or network problem.
Steps to Reproduce:
- Log in to Battle.net app on Android
- Launch Hearthstone or return to Battle.net
- App requests login again after a short time or relaunch
Expected Result:
Login session persists as normal.
Actual Result:
User is repeatedly prompted to log in despite successful authentication.
Additional Info:
Blizzard Support GMs have reviewed this case and confirmed that backend/developer involvement is required, as mobile session state cannot be modified by Game Masters.
