I am facing issue with App review. I have submitted by app for review since many days but the review team is rejecting the app saying that they are not able to login into the app. I have tested my app every time before submitting and it is working fine. I have also tried running the app in multiple regions and it is working fine. Even the support team says that they can login into app but the review team denies it.

Do anyone know what could be the reason? Any help would be appreciated. Thanks in advance.
