iPhone XR not ringing when calls from my contacts come in and not showing calls in recent calls list
For the past couple months I've noticed some calls from my contacts list wouldn't ring and I'd either miss them or they would go straight to voicemail. Yesterday I had a Doctor call, who is in my contacts, and it never showed up as a call missed just went straight to voicemail. I've checked all settings so many times that I'm numb. I do not use the "do not disturb" setting and it's not on. I'm running the 14.7.1 iOS. I've even turned off the "silence unknown callers" tab and the contacts are still not coming through EXCEPT the other day for the first time and the only difference was I was away from my house, I was sitting in a parking lot when the doctor's office called me. Today a couple "unknown calls" came through but they don't show in the recent list as either ALL or MISSED. Any assistance would be greatly appreciated. I'm exhausted.
iPhone XR, iOS 14
