Can not download ANY app via cellular data
Hi!
I've run into a problem with my iphone 6s which has served me very well all these years. Problem is - i can not download any app from Appstore via cellular data, when i press on "Get" button, it thinks for a short moment and then button goes back to "Get" and nothing happens.
When I use WiFi - no problem. I can download and install all apps. It means that this is not problem with storage.
Today I found out that there is other things I can not do with cellular data - when in Apple ID, i can not Open Payments & Shipping, it shows "Loading Payments" and then goes to "We've run into a problem. Please try again later." Again - there is no such problem when i do the same action via WiFi.
What is this? Mobile operator problem? Still all web pages works fine via cellular.
