Found a workaround to be able to move apps and folders. Specially useful if you are trying to move them to another screen. Move the app/folder to the Dock first (bar at the bottom of the iPad). You have to be patient, though. Press on the app/folder. Keep pressing until it jiggles, disappear, and appear again. Move it to a position in the Dock. Again, wait a few seconds until the Dock re-arranges and the app/folder settles. Then, press the “Done” button at the top right. Now, side scroll the screen until you are in the window you want to move the app/folder to. Press on the app/folder icon on the Dock until in jiggles and settles (a few seconds again). Then move the app/folder to the window and keep pressing until the app/folder and window rearranging settles. Then press “Done” again. Takes some time, but it works.
