It could be a problem with metadata synchronization on the various relays.
For example, on Iris, my avatar and lighting address are not updating.
Try using this site to check and update:
Here is my profile and feed in Damus vs Primal.
Notice any problems?
Many missing posts, different avatars, anything else?
In nostr how am I supposed to know whether Damus is broken or nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s is censoring me?

Why are my posts missing? Is that normal too?
It depends on which relays you sent them to and whether the settings of the two clients are identical.
On Android, I have my private relay on Citrine and my notes from Amethyst are always up to date, but if I read on a client that does not accept Citrine, sometimes I don't see my updated notes.
