Illustrator on Ipad doesn't work

Hi. I paid for an Adobe Illustrator subscription on iPad yesterday. The payment went through, and the subscription was paid. The app worked fine until lunchtime today. Then I was kicked out of the app, and when I tried to log in again, the message "Adobe has suspended all new sales of goods and services in your country" appeared. Does anyone know how to fix this?

P.S. I've tried signing out and logging in again,and I'm sure I've paid as I have the invoices
