After last changes from Facebook side on 4th april, Other apps are no longer able to fetch / post on groups you don’t manager, only “Facebook for iPhone” or “Facebook for Android” can perform those actions
    To be able to post On groups your don’t manage you need to use “Facebook for iPhone” or “Facebook for Android”, make sure you open Facebook Poster on the same browser you use Facebook.com and make sure you logged in on Facebook before generating token.
    To reduce getting checkpiont from Facebook It’s recommended to enable “Use two-factor authentication” and “Get alerts about unrecognized logins” Settings -> security -> Setting Up Extra Security .
