I have been using this app for the past few years now. My current mobile is OnePlus 7 pro. Most of the times, caller ID is not displaying when I am receiving a call even if I don't attend the call and keep waiting for few rings for ID to display. Hence, I am forced to attend the call without knowing who is calling. After hanging up the call, a pop up is appearing showing who called. What's the use of that late response? Only rarely it shows the name when phone is ringing. This delay often makes the app useless.
