XR iPhone does not ring when called

Ever since the last update, my phone picks and chooses to ring. The phone is on loud, do not disturb is not on, and I cannot find any other settings that would disable the ringer. An example of what is happening is: My wife would call, and the ringer won't come on, but a random number calls, and the phone will ring.

Check the Mute switch on the left side of the phone near the top.

If it's a specific contact go to that contact and check to see if it has a custom ringtone, and verify that you have that ringtone on your phone.

use the side control and flip the switch to up for ringer.

Did you ever resolve this? I have the same issue!
