Android Update Causing Restore Purchase to Fail
Some time around late January 2026, Google pushed out an Android update which caused an incompatibility with the existing v6.6.3 build from the Play Store, which would prevent restoring a purchase from working.
Please update to v6.6.5+ from the Play Store and try signing out and back in to restore your previous purchase to fix that issue:
