Make sure both apps use the same set of relays. Head to both apps' edit profile and just hit save, wait about a minute and it should be fixed.

If two relays have different profile information of you (aka. kind:0 events in the Nostr spec) then your client may be confused. Technically, it should only fetch the latest one - but as you can tell, this ain't working so well x) So just make sure your relays all have the latest profile!

i changed to plebstr on mobile and only use mobile now
