Not so, I’m afraid.  This has been happening to me now for over a month, with a card that’s not new with no change of details.  My details and card have not changed in several years.  And just when I think it’s stopped - that is, a few transactions go through without it - it starts up again.  🤦🏼‍♀️
I was just looking today to see if anyone had a concrete answer yet, but it seems not - not on any threads of the same topic.  🤷🏼‍♀️
