Really annoying notifications. That cant be snoozed or partly disabled, until you shut them down completely in the os configuration. Why the hell I still see unread bobbles of the groups or chats that are muted? Where is "count" option in the iOS again? Why my configurations were reset after last update? Where is dark mode? Every new message showing Touch ID on the display. Phone is blinking like stroboscope. Want to delete this messenger and never install it back. So Ill do it. Really crap software. Really mean it. Maybe youve got good protocol, but iOS development sucks. Maybe you need more money then? Make a subscription!
