Zotify seems to work but i got logged out of all my devices when i used it.

I understand that ActivityPub ≠ Mastodon however from their UI it feels like a fork of Mastodon with all the Meta bs on top, i might be wrong but it just feels like they saw the opportunity and took. I say this because of even the naming of the app which seems like a direct reference to the Mastodon threads.

I think they’re using an instance of mastodon
