My iPhone doesn't give any notifications or ring for calls.
This is a follow-up to https://discussions.apple.com/thread/253530485?page=1, but with more info and corrections for what I was wrong about.
I thought it was originally just messages, but now I've found out that my iPhone does not make ANY notification sounds at all. It vibrates, but does not ring for calls, or play any notifications. It doesn't make any sounds for text messages, reminders, appointments, or anything. That's if it's at home, on the same wifi with my iPad, another old iPhone (with a non-working SIM), and my iMac. The iPad will make notification sounds, but my iPhone won't. (And, in the past, ALL my devices would sound notifications when I got a call or text.)
When I'm out away from the house, not on the same wifi network at all, there are still no notifications at all. Vibration, but no sounds. I tried changing the ringer volume. While I can adjust the slider, it still shows the ring volume as deactivated, as shown in this screen shot:
The mute icon stays there - I can't turn it back on.
I have checked in Notifications and text and ringer are on. I have checked in the new Focus mode and it's off. I did set up two macros, one to turn on Do Not Disturb and one to turn it off. I've made sure it's off - checked in settings and ran the macro to turn it off a number of times. (Other than that, I have not set up focus modes yet.)
I can't think of any other settings to check for notifications and I'm not getting any. I can't find anything that's off that should be on.
