I am in a circular loop, I try to update apps already purchased and am directed to the iTunes store to check downloads, there are none showing just a greyed out screen with iTunes terms and conditions link in the middle of the page, nothing else. The download shape doesn't respond at all. If I try to buy an app it tries to download then says vie already purchased it and to go to iTunes store, same thing happens. I've checked all settings for app store, checked account, signed out then in again, gone onto iTunes store multiple times to find a way out of this issue. Can anyone help please or is this the end of my iPad? It is 13 months old, has it tired of life?
