Hanging up hangs for about 30 seconds on Lumia 950 with Windows 1909.

[Revelation1714]

App seems to work fine, except hanging up a call hangs for about 30 to 45 seconds...

Also, one time on a call WoA kept notifying me that I had an incoming call.
But it was the same call I was already on.
That one was a little odd... But it only did that one time.
Not since.
