I have DnD on where some favorite contacts are allowed to go through. This works as designed for regular phonecalls.
These contacts can also call me through Whatsapp or Telegram.
However with DnD mode on, if they attempt to call me through Whatsapp or Telegram the calls do not go through. I have even tried to allow full apps to go through, meaning any Telegram call or Whatsapp call but they are also being silenced by DnD.
Is DnD broken for apps calling to come through? If not and you have it working, what settings are you using and can you exclude specific contacts in Telegram/Whatsapp to go through while others are silenced ?
