Screen Time hijacked my apps

A peculiar thing happened to me. It looks like someone attacked my iPhone Xs through Screen Time or was it the Screen Time itself. After I turned on "share across devices" screen time restricted almost all my apps one by one. Some of them disappeared completely. I wanted to remove all the restrictions. Now there was somehow 10 min usage limit, which I certainly did not put there. A passcode was required to change it. But passcode had also changed somehow and could not be changed like support suggested (https://support.apple.com/en-us/HT211021). I hadn't changed my passcode. To change my passcode I had to do factory reset. Only after that did I have this opportunity "forgot passcode" and then I was able to change the passcode. Now I was able to remove all restrictions, there was none. But still I could not get all my apps back. I saw them in App Store, but the cloud sign was inactive. It was next day already, so the restrictions should have definitely ended. I had to turn off Screen Time completely to get my apps back. I would like to use this option again, but after such nonsense, I dare not. It took a long time (almost 15 hours in total) to get my phone working properly again. A local apple reseller helped me with that also. They had never met anything like that before
