Dear Team,

We are currently in the process of testing the WhatsApp Business Embedded Signup Flow using our previous test account to ensure that the whatsapp_business_messaging and whatsapp_business_management permission (App Review) requests are functioning properly. Unfortunately, we have encountered an error that reads "This business account didn't comply with our Advertising Policies or other standards," which is preventing us from proceeding with the testing.

We kindly request your assistance in resolving this issue so that we can ensure the accuracy of the flow and proceed with submitting the App for review. We have verified that Facebook is not accepting App Review from the https://developers.facebook.com/docs/app-review/submission-guide/common-mistakes/ link under the development app. Therefore, we would like to complete the app development with testing at our end and then submit it for App Review.

I have attached a screenshot of the error in this comment for your review. We appreciate your help in resolving this issue and look forward to hearing back from you soon.

Thank you for your attention to this matter.

Best regards, Rigel Networks Pvt. Ltd.
