I received my invite to convert from a pre-paid card to the full CA so I went through the ID process. When I got to the last stage (Confirmation of UK tax status) I just got ‘There’s been an error, try again later’ when I confirmed that I’m only a UK resident.
I then hit back on the (Android) app and was taken to the send me a card screen?
I think this is a question for in app chat or help@monzo.com to confirm for sure, rather than for forum users - who can give helpful info but can’t confirm.
