Payments all declined

So I activated my curve card and added my cards to it, I was using it fine for a few days but since yesterday all payments are declined no matter which card I select in the app.
I have sent 3 messages via the app and I’ve had no response.
Can you please tell me what the problem is here?

Hmm that’s definitely weird, when I’ve had an issue it has been with the underlying card but clearly not the case here if you’ve tried different ones. I find in-app messaging can be a bit buggy so I’d try emailing

In had 1 problem yesterday
With the message from the curve app, there was an error, please ty again
I switched card just to see, both card are revolut card, 1 mastercard 1 visa card
And it worked
Didn’t have any problem today
