Thank you for reaching out to Microsoft QA. It appears this issue is related to the retirement of the classic Azure Redis Cache service. Migrating to the newer Azure Managed Redis service resolves this issue and provides full compatibility with Private Endpoint approvals in SAP Commerce Cloud (CCv2). We recommend using Azure Managed Redis for better integration and a smoother experience with SAP CCv2 Private Endpoints. If you need assistance with migration or further support, please let us know.
Hope this helps. Do let us know if you have any further queries.
