Can't view Curve Card limits

Hi, every time I try to access the Card Limits page in the app I get a message saying “The callable returned a null value” and I see an empty screen with the title “Curve Card Limits”.
What could be the problem?

I use Android 10 (EMUI10), the Curve app is updated to the latest version, my Curve card has been activated and is currently unlocked.
I have already paid with the app multiple times.
