This morning, I added my Monzo card to my Coinbase account and then tried to use it to buy £500 of Bitcoin. The transaction was refused by Monzo. So transferred the money to my old account and made the purchase through them.
Was it just a glitch that refused my transaction? Or do Monzo have a reason to block transactions from Coinbase?
There has been some discussion on here (try the search?) but I don’t recall seeing a timescale yet. I think they want to do something about the dreadful 3d secure UX
