Steps to reproduce the bug

1. Have a call in progress.
2. Receive a second call.
3. Call number 2 is put on hold, as expected, and you are given the options to merge the two calls, or to flip the two calls and put the first call on hold.

Expected behavior

Both options (flip and merge) will work, allowing you to merge the two calls.

Actual behavior

Neither work, you are stuck with call 1 and are not able to respond to call 2.

Screenshots/Screen recordings

Additional information

This is likely related to #199 , which happened to me on an earlier version.

I think I observed something like this too back when I was testing some in-call UI improvements.

My issue. There is nothing, button or window, that allows to switch back. I just have my home screen showing. I pull up the phone app again then hange up and then call the holding number back.
