I have had the same issue several times since upgrading to ios14. I am now on 14.4.1 and literally upgraded from a 7 plus to the iPhone 12 Pro Max this week. Same thing. I go to move an app into a folder and suddenly several things happen. Several folders of apps disappeared and put the apps on the home screen... but of course they are scattered everywhere. (Not all folders dissolved, just some.) Waze moves to another page, so I try to move it back but it gets stuck binding with another app so then I try to move it back out... it will not allow it. Then later it did but took forever. A particular utility app won’t allow me to drop it in my utility folder... but will allow itself to be placed in other folders. The finance widget showed up on my 3rd page randomly. I hadn’t downloaded it previously. Another random widget showed up on one of my pages. The questions remain - why on earth has this not been fixed? It leaves us with terrible and disorganized home screens, and the whole point of a smart phone is to enhance your life and help you be more efficient and organized... it’s supposed to feel good and this doesn’t. You don’t even want to take the time to fix it because you know it’s going to happen again. Secondly, why hasn’t apple made it where we can “cut” and “paste” an app where we want it within the grid? Why do we have to play games with holding our finger on it and tilt our head just right to swipe through 4 pages to hope that it drops into the right folder? And we all know that along the way it’s going to try to bind with another app and we will have to pull it back out and try to keep going etc. Sometimes moving one app around takes several minutes. With all the tech, it’s ridiculous that this (cut and paste an app to a new location) hasn’t been added as a feature. Some of us carry a LOT of apps and rearranging them is a nightmare with the current system. PLEASE fix this issue. It seems small, but when you hate looking at your disorganized phone... it’s really a significant issue.
