Same here, russian bank, expected payment date was March 7, still no payment, Balance carried forward.
I have a hypothesis why this happend.
Apple recently made some changes to the paid application agreement. They do it quite often and usually you just need to go and click on the "I agree to the terms" checkbox. And the last time it looked the same. There was a notification in the main page of Appstore Connect telling that there are some updates in agreements. So as I remember I clicked on the provided link and agreed to the new terms. After that there were no notifications shown on the main page. So I thought all is fine. But after I did not get paid I started investigating what could be the reason of the issue and I found that the status of the Paid Application agreement is not "Active" and green but something like "pending user data" (don't remember precisely) and yellow. When I opened the agreement there was several new contacts field that should be filled in the Contacts section: Financial, Technical, Legal, Marketing. So I filled those fields with my contact and the agreement status became "Active".
Do you think that the fact that the agreement was not in the Active state on the date of expected payment coud be the cause of our issue? Do someone experiencing the problem have these fields unfilled?
