Earlier quoted context omitted.
Do you have plans to address the fundamental unreliability of your chat? It regularly messes up message delivery (failed delivery, delivery multiple times, delivery out of order) at the slightest sign of network instability or server trouble. It's the worst I've seen from any sort of chat application, ever.
Yeah - there are more plans to handle more robust message retry logic. But it's a pretty hard problem to handle. Duplicate message delivery has been fixed for a while though - although there are some rare cases where it can still happen. I don't think out of order delivery is possible as the messages are processed one at a time - but if you have a specific example I'd be more than happy to take a look.
Happens to me incredibly often after I lose my connection while sending a message on Android 6.0.1
