thanks Ashley I hear what you say but they are named "Experimental features" in the OS settings. Some of them are on, some are off. By default. The settings changes in every version. If you own any ios device you can just check it out. (they are not all off by Default!)
These two settings were off in ios 14 (if I understand correctly), but they are On in ios15, but still named 'experimental features' though.
I understand what you say here, but in this specific occurrence it seems like Apple changed the experimental setting in v15 (to On) and it was Off in v14.
But when users change it back to the v14 settings they got it to work again.
That's why I just wondered if you have any insights in this. I fully understand that this is an ios/apple thing, but since I know you understand those frameworks more than at least I do maybe you could shed some light.
Here are some discussions
