FB to post app review rejected

Hi my site was working fine with the old shared login credentials but stopped. So I created a fb app to simply retrieve fb posts from a business page I am an admin of. But the FB to post function still fails? log: [4-Nov-2019 08:38:50 America/New_York] Unrecognized API response: { "error": { "message": "(#10) This endpoint requires the 'manage_pages' permission or the 'Page Public Content Access' feature.

From fb: Thank you for your submission. After review, your app does not require Page Public Content Access for its intended function demonstrated in the screencast. The only valid use case for Page Public Content Accessis to read and analyze insights from other pages where you are not the admin. Your app's intended functionality can be supported by the Manage_Pages or Read_Insights permissions. For more details on how best to incorporate these permissions, please visit our Permissions Reference. You might also find it helpful to visit our Developer Community Forumto find related content or post new questions. Thank you. I then submitted as manage pages and was again rejected from fb: manage_pages feedback While your screencast and notes provide a valid use case, we were unable to verify this use case when we logged into your app. Please ensure that your app has correctly integrated the requested permission, and resubmit for review so that we can complete testing. Not sure where to go from here but it does not work. Please advise. thanks
