Mine broke and I couldn't get it working again.
So I ITed the hell out of it. I uninstalled and reinstalled it, and now it's working again.
No idea why that worked or what the problem was. Although I have noticed that apps installed via f-droid are hit and miss when it comes to updating correctly, so perhaps it tried to update and got stuck?
