At some point in the last few weeks, the T-Mobile app has become limited to users whose iOS App Store account is located in the Netherlands.
The app deleted itself from my phone and now can no longer be installed.
I cannot change my App Store location because of the bank account used to fund it, and because of some government apps that depend on its current location setting.
However there seems to be no reason for this sudden limitation on the T-Mobile app.
Is anyone aware of the change, why it was made, and whether it can be restored to its previous situation?
