Facebook says no more Dev apps sneaking into production

Facebook has mandated that all apps developed for its platform must be set to Live Mode before they can be used in production. The change means that apps that are still in Dev mode “will not be able to manage any assets (for example: Pages or ad accounts) that aren’t owned by their own business or access the data of any users who aren’t associated with the app.” Developers will still have to go through the social network’s App Review process to access “advanced user permissions and/or business permissions”.
