I have a Rails web app that allows the user to manage Ads from Facebook. This is done through the Koala API as followed:
graph = Koala::Facebook::API.new(access_token)
This method stopped working, and it is giving me this error:
Koala::Facebook::ClientError: type: OAuthException, code: 278, message: (#278) Reading advertisements requires an access token with the extended permission ads_read [HTTP 403]
Any advice please ?
