iPhone 11 no text notification ring...YES I have every fix and setting out there.

For the past 3 months, the text notification ring has not worked but occasionally.

I have reset, changed, and tried several rings for my text messages. I have checked every menu, possible settings and all buttons.

I now daily attempt to change ring, reset phone, change ring again, check again all buttons, settings and yet it still will ring perhaps once or twice a week at random, despite getting messages daily.

My own texts from my iMac Pro won't even get a murmur from the iPhone 11.

I counted at least a full page of iPhone 11 owners posting questions here about the same problem. So I'm not alone, but that's not much of a fix.

No, the ringer is not off. No, the volume in notification, on the phone and in rings are all to max. Yes, it is an old phone now but the text ringer worked like a champ for years.

Is there a definitive fix for this stupidity? Is this one of those asinine update debacles like losing my myriad of specific pinned saved map guides that take hours to recreate every time I update?

Any help beyond all the usual suspects would be appreciated.

Thank you
