Something recently changed when generating a Facebook page access token, as none of the guides I can find work anymore. Even Facebook's guide () doesn't work. Following their guide, I get an empty array when I query the accounts endpoint with the required permissions.
I found a post saying that I needed to add read_insights, so I tried that, but it was still an empty array. Finally, I requested ALL permissions, which returned the page access token. This is not ideal. Does anyone know what permissions are needed to generate a page access token on API v22?
