As you can see in the screenshot above, I got Facebook app review approval but now I tried to access Facebook public page posts and comments per page. Still, I am getting bellow massage in R Console:
Error in callAPI(url = url, token = token, api = api)
:
(#10) To use 'Page Public Content Access', your use of this endpoint must be reviewed and approved by Facebook. To submit this 'Page Public Content Access' feature for review please read our documentation on reviewable features: https://developers.facebook.com/docs/apps/review.
