Tusky 1.1.2 is now out on google play! https://play.google.com/store/apps/details?id=com.keylesspalace.tusky
It primarily addresses crashes and login errors, but there's a few small additions. Also a french translation was added and updated german translation.
@mjd Sorry, you might have to reinstall or clear the app data. I ran into the same issue testing a change I made. There was a piece of code that was supposed to reset a bit of background data the first time this update runs, but it sounds like it didn't. And now it's trying to pass a new redirect URI with an old key it had saved, and they conflict.
So clearing it out should fix it.
@Tusky Woot! That totally fixed it! Now to get it working on mastodon.cloud authentication...
