My cousin downloaded an app for me on my iPad Air while using his Apple ID. I signed out of it, and logged into mine. I updated my device to iOS 10 after I had to temporarily delete apps due to low storage.
Bloons TD 5 was one of them, and after going to the home screen, it was greyed out and it said Waiting. I tried to delete it, but there was no X. By the way, my cousin never gives his Apple ID password to anyone, since it is his mom's Apple ID.
Apparently, I pressed the power button, and pressed it again. I went to the home screen, and it was greyed, but the name was showing. The X showed this time, and I pressed delete, however, it was still there. I tried going on my computer and deleting it from iTunes, but none of my apps were showing and iTunes wasn't able to check for updates, since it was looping.
I tried rebooting, but it changed to Waiting. I cannot reset because my parents put a restrictions passcode on my iPad Air even though I'm like 19. They won't tell me no matter what. It doesn't show in storage, and there isn't anyway of getting my cousin's Apple ID password, especially since he lives far away.
