Mac doesn't notify me for incoming FaceTime call
I'm having this Mac since 2020. Earlier, I used to receive FaceTime calls on my Mac without any issues from other iPhone or Mac. However, now, I can't (Idk since when). The outgoing FaceTime works fine. In fact, I can also see a notification(in FaceTime app) that someone FaceTimed me, but not seeing anything to receive a FaceTime call.
I tried sign out / sign in FaceTime app. Restarted Mac many times.
Please suggest. Thank you.
