Then go to that npub and look at the "muted by" tab. If you don't see them there, adjust the relays.
Yeah maybe it’s not a mute issue anymore. Earlier, I got a notification in Damus. But when I went to the app I couldn’t find it at first. Eventually found it hidden under “note from a user you’ve muted” which sent me on this journey. But now, looking at that conversation in Damus, it’s no longer hidden. So I must have unmuted or something. 🤷♀️
Maybe digging it out lifted the mute.
