I've not had a day without issues. I don't know if this is something wrong with my account (instagram), but it's so unreliable that I can't trust that what I see in Texts is actually how the conversation looks like. Funnily enough, I ran Beeper in parallel as backup.
Weird things from a message missing in between other messages, new messages not showing up at all, messages I send not arriving, etc.
(The iOS app is on a completely different level with it not even refreshing my messages most of the time until I disable and enable certain accounts again. But it's in TestFlight so I'll treat it as a beta and not expect too much polish yet)
I've religiously submitted feedback constantly to them, together with console logs and error dumps, but now my trial expired and I just can't justify paying for it in the current state :/
