For some reason, I messed up my iPad and now when ever I try to download an app I already purchased, I have to type in my Apple ID password where before hand I could download it straightaway. I don't have this problem on my iPhone and they both use the same account.
Is there a way to fix this so updating an app or downloading a previously purchased app on iOS does not require a password?
Also I set it so that the password requirement is 15 minutes and free apps do not require a password, but they seem to have absolutely no effect (Settings>iTunes & AppStore>Password Settings)
