Is this a bug, or an undocumented feature provided by off-shore developers? I’m guessing we will never know.
I’m no Apple fan, but most likely a defect. It happens in ALL software. With a little over 16k linux redhat’s we maintain, the security patching is never ending... just like with iOS, MacOS, Android, Windows, etc etc.
I like the delay in smart phones from when you hit the button to hang it up and when it actually hangs up and cuts the audio. I stay on and listen until it does finally cut it. Caught my adult kids talking crap about me many times because they thought the phone was hung up and I couldn’t hear them. lol
If you are going to dump on who you just got off the phone with, it is a good practice to wait about 10 seconds after you hit the button before you do.
Apparently Apple has shut down Group Face Time.

And more than likely I never will.
It’s an apple feature
Just the other day I listen in on some guy named Swordmaker. He was saying how much he likes Microsoft Windows 10 : )
