One of the novelties of Apple in its iOS 15 is that of alert users while trying to speak when they make a FaceTime call and have the mic muted. This feature may seem silly to many users, but it is not.
It is a kind of reminder in the form of a notification that allows the user receive an alert when the FaceTime call is active
The truth is that the changes implemented in FaceTime are many and varied in this case we have one that allows us to stop fooling around when we are on FaceTime call and that is who never had this thing of talking with the microphone cut
Nowadays, with the coronavirus pandemic affecting the whole world, calls via FaceTime or similar are very common, so it is possible that while you are on one of these calls, you will be silenced and try to talk, with the arrival of iOS 15 and iPadOS 15 will no longer happen to you or at least the system will warn you. What surprises us in this regard is that at the moment in beta 1 of macOS Monterey, we do not have this notification available When we use FaceTime, we imagine that Apple will add it soon in the next versions.
