There is currently something going on over at Lemmy.world causing authentication issues. This isn’t a memmy specific issue but is also plaguing the PWA. https://lemmy.world/post/1364490
Until this is fixed, the best bet it to just keep “retrying”. This would explain some of the issues I thought were linked to issues inside the app but might be something else.
I have an update ready that will fix a bunch of these internal issues with the app, but unfortunately it’s going to break Lemmy.world terribly for anyone using it, so I’m going to hold off on releasing that until they figure out what is going on.
Same here on the Voyager web app. I just got the Memmy app and it seems to be slightly more stable for the past few minutes, FWIW. I just started this account today and thought it had to do with signup delays.
