The relatively small number of building societies who have current account customers have to. This includes Coventry although I doubt they make their savings accounts available via open banking.
Pretty sure the majority of building societies, who generally don’t have current account customers, won’t bother with open banking.
What was the story with amex? From what I’ve gathered from posts dotted around the place they have an open API but it’s slightly different to others? Is an integration being worked on or are Monzo waiting for something?
It’s very likely the most popular credit card among Monzo customers so almost certainly being worked on. Here’s a good explanation of why it’s more problematic than other connections
Metro might prove problematic because they don’t support Open Banking via APIs. They provide access via a method called Modified Customer Interface (MCI) which is a bit like screen scraping and I suspect Monzo wouldn’t support it. The same issue exists with The Co-Operative Bank, Smile, and John Lewis Finance
I’d suggest customers of these banks/cards should get onto them and urge them to support Open Banking APIs instead of MCI.
Don’t know if it’s been said, but after just playing with connected accounts a little bit, I notice now the “tapping home” action cycles you through all your top-level accounts, including the connected ones.
I would, personally, like the ability to turn the connected account cycle off - I’d want to switch more readily between Monzo / Monzo Joint than the others, as I use these two accounts almost daily.
Appreciate that’s not the case for everyone, but I think that behaviour would be nice to toggle on off depending on use.
