I clicked on a link to join a GroupWatch, but the GroupWatch is unavailable. Why?

If there are already 7 people in the GroupWatch you won’t be able to join that GroupWatch.
If the GroupWatch stream has ended, you won’t be able to join the GroupWatch. You can always start a new GroupWatch.
If you have exceeded the limit of 4 streams at the same time on one account, you will not be able to join the GroupWatch.
If GroupWatch and Disney+ aren’t available in your region, you will not be able to join the GroupWatch.
If the GroupWatch title is not available in your region, you will not be able to join. You can always find another title and start your own GroupWatch.
If you are logged into a kids profile, you will not be able to use GroupWatch.
If the GroupWatch is for Premier Access and you have not unlocked the title, you will not be able to join the GroupWatch
