I have been paying $10/month to use Language Cloud in Studio 2021 now it says Subscription expired - payment blocked. I cannot see where/how to update payment if that is the problem. Could someone help me please.

Suddenly I am told that my language Cloud (NMT) has expired - payment blocked but I cannot see how to update payment details. I see that previously this was a migration issue. Could someone please help me as I have been paying $10 for as long as I can remember to use this - I used Studi0 2021 - many thanks
