Exact same thing with Chromium.
I am authenticated. Alby works & I see my picture in the login box. Then I click ok.
But that's it... I cannot access my profile page. I still see the login key in the top left corner.
Works fine on Iris for example. Not Nostrgram for some reason. 🤔
Chromium and Firefox clean, brand new & clean. No other extension. Only Alby.
Same problem. Login icon doesn't change.
I can read my notifications & decrypted DMs, but that's it.
Can't even post a reply.
I had hopes... guess I'll rebuild my following list from zero 😔
Have a look if you have time, something must be broken...
Open the Developer Tools -> Console in Chrome when you login and see if it gives you any errors. The error will appear in red.
