Screen Sharing app seems to be running in the background during phone calls.
If I am on the phone and we hang up with each other and I double click the Home button on my iPhone 8 Plus, to swipe up on the Phone app, I notice a blank transparent screen running and it is labeled as Screen Sharing. I updated to iOS 15 yesterday and was curious if anyone else is seeing this. I have attached a photo for reference. I have never even seen this app before.
