Are you using #Amber? There is a known issue with Unified Push & ntfy. Might be what you're experiencing. nostr:nprofile1qqs827g8dkd07zjvlhh60csytujgd3l9mz7x807xk3fewge7rwlukxgpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszrnhwden5te0dehhxtnvdakz7qgswaehxw309ahx7um5wghx6mmd9usjfpck

The push notifications are not working if you are using amber. In the next release of amethyst it's fixed
I was not using it, then I did use it, but moved again my nsec to Amethyst Play version, at this point I got a couple of notifications but far from all of them. It's really random.
