HI 🙌,
it happened to me also.. it is possible to delete a card with out blocking it / freeze it... at least for DigiCard.
I thought it was not possible to request physical cards for DigiCards but it is possible... at least now.
I tapped on the "Get a Physical version" button and then the request for the physical card kicked in.
As I did not want that, I tap then on cancel request.. and when that happens.. the card gets deleted.
It is a bit weird... but that is how I deleted a card with out freezing/blocking.
The card is gone by the way, no way to get it back.
Hope this helps
GG
