In an effort to guarantee the best user experience possible, Facebook is now doubling down on improving data practises and security. They have recently announced that they'll be making changes to their platform policies to ensure their user data is well secured.
If you do see an error while logging in or connecting your page, it is because they have temporarily paused their app review process which includes the ability to connect/reconnect bots to any Messenger app/platform like jumper.ai and others.
Note: Our current sellers who have already connected your Facebook and Messenger accounts are not affected. You should be able to continue selling and jumping your sales 😄
