@_elena My pleasure!
And sorry about the issue you're running into. I presume you're using your mastodon.social account? (I know you have a few, so just making sure.)
I was able to log in with my m.s account and it worked, so this is a bit tricky to debug, but let me poke around a bit and follow up.
Thank you so much for trying this out!
@stefan Thanks Stefan! I tried multiple times with my Mastodon and Sharkey account (calckey.world) – they both produced the error message.
Let me try with Pixelfed now... and if that fails, Friendica 😅
