I waited until 15.1 was released to avoid the initial bugs and complaints, but unfortunately I discovered the same only after I upgraded last weekend. I tried Clean Up many, many times, but it's really really awful. Such a weird move from Apple looks so crazy because many photography communities buy Apple hardware exactly to enjoy native apps like Photos (including me). Unless I'm getting too old in digital photography, I can't think of any serious photographer or expert advising Apple on this. At least at this point, AI should be welcomed as an additional help for beginners, but never as a replacement of a very important tool to all enthusiasts and professionals. One of the possible ways to have AI getting along is to learn the patterns of how we individually use each tool and try to repeat it when asked, but never cutting our "natural arm" by replacing it with a "cyber alternative" without any way back. Let's wait and hope they fix it on 15.2.
