ios – When I try to update existing free apps or install new ones, I enter a payment loop "Check Required"

On my iPad (iOS 12.2), I try to update my existing apps. The App Store requests that I authenticate with my Apple ID password. He then brings me to the payment information screen, where he asks me to configure my payment method.

I select "None" on the payment method screen, because I only plan for the moment to update the applications and install the free ones on this iPad. After clicking "Done", the Apple ID authentication box opens again, which brings me back to the payment mode screen. This loop continues indefinitely. I can not update my apps or install new apps, even free ones.

In the settings of my App Store, I have disabled the setting "Require a password for free downloads", but that does not change anything. I can not install or update free apps.
