verification pending

We are still encountering issues with access verification for the access share and app access process. During our previous conversation, one of your executives assured us that this case would be handled, and we would receive a follow-up call within 24 hours. Unfortunately, we have not yet received any communication.
For reference, the case ID is: 523982227308334. We are specifically facing problems obtaining app access for API integration with our custom CRM. To complete this task, we require page access from the main account, as these permissions are essential for granting the necessary access.
Currently, we are managing three accounts for ads and business purposes, and the client has granted full access. However, the system still shows “verification pending.” Despite our efforts to resolve this, we haven’t been able to find a solution. We need your guidance and support to complete the access-sharing process successfully.
Please let us know if any additional information is required to expedite this matter.
Thank you.
