I know many instances are not upgrading until the majority of bugs and issues are resolved. In the meantime if Jerboa got upgraded (it looks nice, BTW) then it won't play nice with the older versions of Lemmy. On Saturday I discovered Connect for Lemmy inside the Google Play Store.
I figured for us who need something to read on our phones while we poop, this would be good until our instance gets updated.
Whoops. Just discovered I'm having issues posting or commenting with Connect while in my instance. I'm guessing you do have to log into an instance that's upgraded or view everything in a browser. Bummer.
I believe it's just hard baked into the phone's software. You'd have to jail break it to change it. Try a news app for your needs?
