Cant get back to my current call on iPhone 13 IOS 17.4.1. Green button is at top left but is just goes to blank screen.
Often when I am in an active call, or meeting, but my phone is on the home screen, when I press the small green button for the call at the upper-left, my screen will go black, and then back to the home screen. I haven't figured out the circumstances where the call will eventually open.
