Receiving a weird error when signing into a 2nd instance account

Great job! Lovin’ the app so far.

My only grievance and humble request is that the post screen when opening-loading app should have the same cute, tiled mouse logo.

Thank you for considering my request. I appreciate your time and attention.

Please forgive me for my ignorance on the subject, but is it possible to create a Mastodon account add to a Lemmy app, e.g. Memmy?

Or are Lemmy & Mastdon two very different platforms, Like Facebook & Reddit?
