Adding Paypal as payment method

After checking on the Apple website that Paypal is supported as a payment system in Italy, I decided to add it.

I then went to App Store / Account Settings / Payment Management, I chose Paypal and logged in to my Paypal account, did the 2fa verification and then Boom!

Black screen without any message!!

However, the notice arrives from Paypal for the access made.

I tried 4 times but nothing... I'd say mega bug!

Sonoma 14.4.1

Has anyone had the same problem?

Does Apple know?
