How do I add people to People and Pets or photos to Shared Albums?

Is it just me or has it become even MORE difficult to add photos to "Collections" since the iOS 26 upgrade? Not only did I lose one (very important) person from my "People&Pets" collection, when I try to "add more people" I get only a few random new faces and then the whole interface freezes - even clicking the "x button" doesn't do anything. The same happens when I try to upload a new photo to a shared album - I can SELECT which photos I want to add, but then I have only the option to click on a blue checkmark or the "X button" - and neither does ANYTHING - the whole interface just freezes until I swipe it away. And of course we STILL are not able to actively select faces for "People&Pets" - if the AI can't find any, we are out of luck. Pretty lousy for a "8 versions upgrade"!
