My Apps wont update-iPod 5 gen
I had just got my new iPod in April, i was so excited. But just a month ago i started having problems with updating some of my many apps. I will try to update them, it will then ask for my iTunes password, i enter it in and then it says that its incorrect. Even thought just a couple of minutes later i had bought a game and used the exact same password. And even sometimes it will let me update the app, but the it will ask me to update it again to the exact same update. Can someone please help me with my problem.
iPod touch, iOS 8.3
