When I first created my nostr account, I probably didn’t do it correctly. The npub I use is the one I created (?) using nos2x rather than the profile I created from the Damus app. Guessing something similar happened here.

I had both nos2x and Alby and for some reason, Alby had the wrong private key that I never remember having used or inserted 😂 (I must have generated it for one purpose and have forgotten to reset it.) Anyway, disabling Alby and clearing cache fixed it :)
