I use the Open Banking Access Dashboard in the app to manage consents with third party apps (in security, manage apps). Monzo are supposed to show quite a lot of detail here but every connection just says “Account Information ongoing session” so it’s impossible to tell which app is which, how long is left on the access/consent, what data is shared.
The standards for what Monzo should show are here:
Pretty sure not meeting those is a regulatory breach so would be good to sort out!
