I hope I'm posting to the correct area here; if not, please accept my sincere apologies. For the past couple of weeks, I have not been able to purchase apps (even free ones) or buy music for my IPhone. I can select what I want to buy and the option comes up for me to enter my touch ID which I do. It then immediately reverts back to the screen with the listings from which I chose the item and the app or music I want to purchase does not appear on my phone. I have verified tghat my settings allow for immediate download of purchases and that my credit card information is correct; (I used the card to purchase something on another site.) I know the password is correct because I logged in from my PC and was able to view past purchases. What could be causing this weird behavior and what can I do about it? Thanks for any help you can offer.
