That just proves that it's a bigger problem than just one app. Thanks for letting me know that it wasn't Yelp. It's getting frustrating, and there's no way to force it! I've reported it to Apple, and I also reported the problem to yelp, though Yelp isn't quite sure what to do about it. For me, it's a bigger issue than just needing to add something to my calendar for my own sake, but it's a necessity. There are actual repercussions if I miss specific events. Yes, I can add them to the calendar manually, but that takes more time than I have, when the app, which used to have access to my calendar, no longer does and it can't request access. It isn't every app or every account either, because my husband can add events to his through Yelp. We have uninstalled the app and reinstalled it a total of four times now, and still no access.
