Unable to get app
I am trying to download the Mi Carrefour app to use with my Carrefour el club loyalty card on my UK purchased and registered iPad Air 2 device. When I go to the App Store I get the following message, Account not in this store. Your account is not valid for use in the Spanish store. You must switch to the UK store before purchasing. When I hit change store a message flashes on screen saying cannot connect to store and then the App Store appears, but when I search the store the App isn’t found.
Any suggestions anyone ?
iPad Air Wi-Fi, iOS 11.2.6
