I installed to a new iPhone from iCloud backup. Mlem came over fine and had both my accounts in there, but neither worked properly. I could browse ‘All’ but saw error toasts and no subscriptions etc.
I logged out and back in with 1 account and that one (this) is working fine now.
This might be expected behaviour but it was a bit confusing and no meaningful errors were displayed. In case this is unexpected, I’ve left my other account in the kind of limbo so I can get error messages if that’s useful.
Ah, sorry, I just logged back in with this alt, and whilst I just got errors the first time (not sure why), force-quit and restart worked fine. I guess I’ll have to wait for the next phone upgrade :).
