Starting April 22, 2024, Meta disabled the ability for third-party apps to connect to Facebook Groups. This means that Ripl and any other non-Facebook apps can no longer connect or share to Facebook Groups on your behalf.
As for now, we would suggest saving a post to your device (as seen here: Saving a Post) and sharing to Facebook Groups manually.
We apologize for any inconvenience this might have caused, and we will keep you updated on any changes introduced.
