Just chiming in to say I’m having the same issues, split second of interface shows on launch and then black screen (Android, dark mode).
This is true for both my Native app and the web app.
One thing top add that nobody seems to have mentioned yet - both apps are (most likely) logged into #Beehaw. None of my other apps will load Beehaw, either, but Liftoff at least works with my lemmy.world account, but won’t load anything from the Beehaw feed.
So could this be an issue with some instances (beehaw, in my case) combined with some Lemmy update, in combination with something in Voyagerapp?
Voyager is my favorite Lemmy client so this is a very annoying situation 😅
Guess I could try web app in Incognito, see if that works, maybe log into lemmy.world from there. Will update if anything changes 👍
