I've been getting that message "The iTunes Store is unable to process purchases at this time" every single time I open an app that was downloaded or purchased from the iTunes store. My software on my phone is up to date on its current version (iOS 11.2.2). So how can I stop that message from coming up every time I open an app???
The solution for this issue for me was reenter the payment information for the Apple id.
Change or remove your Apple ID payment information - Apple Support
Through the Iphone and Ipad I could not reach this information (unable to reach payment setting error message) but through the Mac Book it worked (appstore account).
The same thing happened to me now I can’t access anything and I’m really furious Because it’s deleted my pictures and iCloud isn’t backing anything up.
