This app is struggling hard since the recent update. Every few hours it loses connectivity, and when it comes back, a bunch of my messages are gone. I can restore from my last backup, but any chats since then are gone. Happened once last night - just happened again for the 3rd time today. It's pointless to try to hold a conversation at this point, cause in a few hours the chats will disappear. And of course, many messages still fail to send until you reopen the app again - like usual.
