ios 10.3.3 update will not allow me to download apps
Just updated my older ipad to ios 10.3.3 (which is the latest ios available). Now, I cannot update any of my apps. All my apps are affected - facebook, messenger, google maps. When I try to update, it looks like it is going to work, the download circle appears and one tiny dot shows and then it stop and displays "unable to download app." Then it goes back to the app update page. I have rebooted, signed out with my apple id, tried restoring the app from a backup, reset my wifi, and several other things ---- all to no avail.
Please help. My ipad is now basically useless!
