As of some time today I am no longer able to log into sopuli.xyz with the Mlem app. I can log in on web fine, and with the Memmy app (currently on Memmy).
When logging in I get an incorrect username or password error on Mlem.
ETA: I am using 1.1.2(782) TestFlight build on iOS 17.2.1 on an iPhone 14 Pro, but having similar issues on my iPad Pro.
Uninstalled and reinstalled and it appears to be working again.
