I noticed that Primal removes a lot of replies. Relays are the same in two clients, but Primal shows less comments to same note. More fun (or sad) that 0xChat sometimes "losing" messages. In group chat one can see 3 messages, on another npub in the same chat there's 2 messages. That's a protocol issue, I think.
Discussion
Regarding the issue of losing messages in 0xChat, is it happening in a channel or an open/closed/private group?
To be honest, I noticed this only once: from two phones of different npubs, the contents of the open group were different - one showed 3 messages, the other - 2. Moreover, these were messages from one person - it was your answers to questions of users in the open group. And one of them was not delivered. The difference between the two devices was in the connection - each had its own network and possibly VPN or Tor.
thank you, will check it
