As the title says, I can't log into that instance from the app ("incorrect login" in the scnackbar), while it works perfectly from the browser. I am using a password manager. It would also be nice to have 2FA support.
edit: I forgot to say, I am very thankful for the app existing, and it's already a nice experience to just lurk.
When you create an account or login, some instances only use the first 60 chars of the password field and ignores the rest. Boost does not limit the password length, and it fails because it is different than the password Lemmy expects.
