I would have rated no stars if it was allowed. Most of my messages aren't delivered in group chats or pv chats. Maybe I have misunderstood the meaning of a messenger app, so please correct me if I'm wrong... Isn't communication the reason that we use such apps? Tell me how can I communicate with someone, when they don't receive my messages? Messages that are sent to them but not delivered... It's been 4 months people, 4 months... Wanna do sth about it?
