I too am afflicted by this issue that was introduced in iOS 16 .
It was not an issue in any operating systems prior. I’ve tried literally every setting Apple has provided and nothing works. I hoped since iOS 16.0 that one of the many eventual version updates would fix this but now we’re on iOS 16.4.1 with zero attention to this massive issue.
I’ve turned off the iOS Calendar App toggle for ‘Event Alerts’ & ‘Events Affect Availability’ for every shared Google Calendar I’m subscribed to. And after a minute the iOS turns them all right back on again without any word to me that my settings are being ignored and overwritten.
My phone’s battery is now suffering because of this. Many times per day my iPhone will start vibrating with notifications that don’t even pertain to me and it will vibrate for minutes on end. There was a time that it vibrated with Calendar notifications for a hour… using up 25% of my battery.
My wife thinks I’m having an affair with another woman because my iPhone will start vibrating with dozens of notifications at midnight and/or 3am. At first she thought it was true that there’s a calendar bug. But now it’s been going on for a year and it’s just not believable to my wife that such an established company like Apple would let it go on for so long. She’s convinced it’s another woman and I’m just covering it up somehow as a ‘software glitch’. She called me a ‘spineless liar’.
I hadn’t considered moving to android devices until now. But if that is what will save my marriage then I have to pick what is most important. I can’t buy a new wife but I can buy a new phone.
I’ve attached a screenshot of over four hundred notifications today and none of them are from calendars I’m even involved in.
