Ahah … This sounds familiar, my app creates documents representing audit results locally, I’ve had a few instances (very few and very random) of the audit documents not synchronising, it’s push/pull, 3.0.2 client,the documents refuse to sync and the users have had to start and finish a new audit (time and money and reputation) … as it has been very intermittent I’ve never been able to reproduce in dev, I will try now with starting with 4G and switching to wifi to see if I can replicate … not sure that ‘replication is behaving exactly as it should’ is an answer.
