Some findings:

1. Have been investigating the message delivery flow, added unit tests and logs to verify in https://github.com/status-im/status-go/tree/fix/group-chat-message-delivery.
2. Could be that Extend peersyncing to sync 1-to-1 messages status-go#4962 is related
3. Trying to ascertain it via testing against different status-go versions.

Having finally resolved ios build issues, was able to verify 2 and 3 - it's a different status-go issue. Continuing debug.

Not reproducible in latest develop, after pulling the latest changes from yesterday.
