Hello TraciM,
I found it with a quick Google search, however I do get the following message.
“This content isn’t available right now
When this happens, it’s usually because the owner only shared it with a small group of people, changed who can see it or it’s been deleted.”
So you are going to need to work on your permissions for the group and its visibility.
Tap or click here to see where the settings are for changing a group from private to public or vice versa.
