SQL Data Sync: Subscription Operation Not Supported During Migration — Request for Assistance

Question

Problem description

I am experiencing an issue with Azure SQL Data Sync, where operations are blocked with the error 'DataSync_SubscriptionOperationNotSupported.' This occurs even though my subscription was previously active and used Data Sync. I need assistance in restoring Data Sync access to complete my migration.

Environment

Azure SQL Database with SQL Data Sync enabled in the West US 2 region.

What I've already tried

I have identified the affected sync group and confirmed that the subscription is active and the sync agent is online. I removed the on-premises member successfully, but adding it back is blocked by the 'DataSync_SubscriptionOperationNotSupported' error. I also reviewed documentation and confirmed that the sync group was previously operational before the issue occurred.

Current status

I am seeking support to restore Data Sync access for my subscription to allow re-adding the on-premises member and completing my migration process.
