This app used to be pretty functional, but it seems that ever since they had the audacity to force me to pay to get verification codes they have also decided that functionality is not a priority. It keeps getting worse and worse, bad call quality often, even if I sit next to my router, messages delayed and not showing for sometimes hours at a time (leading to disastrous misunderstandings), and now I can no longer open messages by clicking the notification, it just shows a frozen blank screen.
