Hi @DTS Engineer We have not yet received any form of feedback from the iCloud engineering team. How should we contact them and obtain support? Looking forward to your reply, thank you

Hi @DTS Engineer, Thank you for your reply. We have completed the migration of the app with a relatively small number of users (com.dhgate.DHgateSeller) on August 12.

Hi @DTS Engineer, Is there any new progress or discovery in this case? Regards
