The Monzo app just closed on me.
Re-launched and got the login screen.
Got the magic link and logged in but got an error screen displayed with a ‘Retry’ link
Retried - it’s logged in but has set all Monzo Labs settings to OFF
Changed all Monzo Labs settings to ON - got new nav back and then tried enabling fingerprint auth - the PIN entry in this flow returns an error, so can’t enable.
Went back to home feed to receive “Some card transactions may fail” error message
Gulp!
