Correct login information but “incorrect username” error

I’ve been experiencing an issue on my iPad where whenever I type, Logseq shows the message below:

To troubleshoot, I logged out, but now when I try to log in, I get the following message:

I would have tried to login with a username, except I don’t recall ever having one.

Has anyone else experienced this? I’d appreciate any help here.

I solved the username/password issue by just changing my password using “forgot password,” However, I’m still experiencing the “Invalid State Error”
