garmin pay unable to verify card

I just got a second hand Vivoactive 4 and I wanted to add my card as I did 2 years ago on my Venu.

On Garmin Connect I filled all the requests but I get stucked at the moment of verification, I select to verify via bank app (in my case Intesa San Paolo, which should support Garmin Pay connection but then I get bounced back.

I tried few times, also removing the card and starting back from the beginning.

My card is a XME Mastercard and I used it without any problems with my Garmin Venu.

Any knew recent issues with the bank or with the validation system? Anyone else facing the same problem?
