DND function no longer works

Don’t update if you need the DND function in the app.

This update breaks the DND function, so that your phone will still ring once and then stops. The only way to put that app on DND now is through the iPhone, but this will block your regular calls too.

Developer Response ,

We understand and share your frustration. Unfortunately, it's down to some changes that Apple has introduced.

Apple has changed the way pushes work, so DND no longer works the way it used to.

To be clear, Apple doesn't want VoIP apps to use their own DND feature at all; they want DND to be used directly on the iPhone.

Even when you are on DND on the App, incoming call pushes will always show the incoming call screen now, and we can't prevent it.
