The Words Classic icon on my Android shows a notification badge (1) that does not reset, even though I have no messages or open moves. How do I reset it?
Welcome to Android Central! Which phone? Go to Settings>Apps, select the app, then Storage, then Clear Cache. You can also Clear Data, but this might delete any locally saved game data.
You can also try Settings>Apps, tap Menu>Show System, then look for something called BadgeProvider. If you can find it, clear its cache and data as well.
