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

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. Another app with a relatively large number of Apple authorized login users has temporarily suspended the migration work due to the problem of not being able to obtain a new identifier. Regards
