This is a rather common issue with Facebook. If you’ve created a new Facebook page or a new Facebook group, it may not appear under your RecurPost account.
The reason for this is pretty simple. When you gave access to RecurPost, you did not select the newer page or group as this requirement didn’t exist back then. Hence, it will work as if you didn’t give permission to the page or group.
How do I fix this issue?
It’s actually pretty easy to fix this. You can simply go to your Business Integration under Facebook settings.
If you are logged in to Facebook, simply go to – https://www.facebook.com/settings?tab=business_tools
Once you’re on that page, click on “view and edit” link under the RecurPost app.
Scroll down on the pop-up and check the box next to the page or group that you added recently. As soon as you do that, go back to RecurPost and try to add it now. It should show up in the list.
