@aembytes ,
When you you rollout a site a pop up message gets displayed which says Rollout successful.
If even getting that pop up the rollout is not complete then please check the permissions of the user on the content.
I think the user lacks permission on the content.
What I believe is the user is able to select the rollout configs and is not able to do a successful rollout
Check the user has sufficient permission to Modify/create/delete permission on content(where rollout is happening)
Still if it is not working then create new debug logger for com.day.cq.wcm.msm.impl.* and check what is the issue.
Hope this helps!
