As of lately, the app has been acting up A LOT. Have you ever written a lengthy message just to have it disapear into thin air as you press send? Or been waiting for important messages to come, only to have them appear one after the other, out of the blue, 5 hours later? Creating conflicts and unnecessary missunderstandings. It is really frustrating and making the app really unreliable, which had never been the case before the few latest updates. Please fix the issue soon...
