Logged on and a few minutes ago I noticed that the minimap button wasn't there anymore, and then when I went to the settings I couldn't find it in Interface>Addons either. It's definitely updated to the most recent version and the Addons menu shows it as definitely active, however it's just completely gone. Chat commands don't work either.

Uninstalled and reinstalled and it fixed it. ¯\_(ツ)_/¯
