Are you still having the issue? I hope trying again later worked?
I used Brave and it was fine. Then I switched to Orion. Also fine (but couldn’t post for a while).

I found the issue! I had previously connected snort.social to alby, but not actually entered my key in the accounts page on alby.
After I did that login prompt showed up 😉
Thank you so much for helping 💖
