Hooray!
I hopefully won’t personally be seeing it for a while as my card was replaced towards the end of last year due to natural expiry, but it will be handy at my next replacement.
Is there any news on showing us a list of the retailers you have updated the details with during this new card activation flow?
I think that would be really great.
Argh bollocks, I quite literally activated my new card three days ago, on Tuesday 
.
Still going through all the merchants to update details!
I smell a conspiracy! There was something dodgy in 3.67 to prevent early insight!
Yeah this would be next level. At a minimum a list of merchants with card details updated. And then suggestions of frequent/scheduled payments that may need updating manually, ideally with direct links to update payment details.
Absolutely, this would be excellent.
It should be possible for Monzo to create a list of all merchants where your card has been used online, try to auto-update all of them, then the ones which are known not to work would be listed separately in a “we’ve tried to update your details with these merchants, but you may have to update them manually” list. It would be very clear to them also have the list of “we’ve successfully updated your details with these merchants” on the same page.
Users would then know exactly which merchants to double-check with.
Hooray @arthur-ceccotti! 
Now it is out in the wild, let us continue here:
