No clue, but if I go to the note and tap on the reactions, I can see everything correctly. Also the dot at the bell icon appears and sometimes I even see a banner to flash for a picosecond... and there is no record of it listed in the notifications.

I sent you some DMs with further findings, so I'm not spamming it here.

The most interesting find is when I send you a @ link to a note id, the zap from the note "magically" appears in the notification tab too. But not before that.

And it's all gone after exiting damus and starting it again. One random old zap is showing, nothing else. Weird.
