We are from Belarus and also received such a message and we cannot continue to work. The status of our legal entity in the Appstore developer account has changed to "restricted". We cannot release new builds or applications, and we cannot transfer applications. There is no data in the "Payments and Financial Statements" section.
This happened without prior notice or request from Apple, which is outrageous and inexplicable! Our company and all of our decision makers have never been on any sanctions list. No account information in our company's developer account has ever matched, in whole or in part, with any "restricted party or one or more parties on the United States Government Consolidated Watch List, Other Government Sanctions List".
