Whenever we try to upload a video via the reels API, it gets stuck on the processing phase. The workflow we use is the same as written in the docs

I am trying to implement Facebook login for Business. I have followed the exact same steps in the Quickstart section. I have also tried involking the login flow manually - https://developers.facebook.com/docs/facebook-login/guides/advanced/manual-flow
My app is in live mode.
Nothing seems to work. Please let me know if you had come across something similar.

We are reaching out regarding the upcoming deprecation of the groups_access_member_info and publish_to_groups features, scheduled for removal for all versions on April 22, 2024. These features are currently integral to our application's functionality, and we are seeking guidance on alternative options or replacement features that could fulfill the same purposes.
Could you please provide information on any alternative features, APIs, or methods that can be used to achieve similar functionality? Understanding these alternatives will help us ensure a smooth transition and uninterrupted service for our users.
Thank you for your attention to this matter. We look forward to your guidance and support.
