That is crazy. I thought Sea World was bad with that, but at least they have signs in their parks telling you when something is closing and team members know, but their app is not always up to date of when a specific ride is closing. Their show times are accurate and if they change they make a park wide announcement. I was there once when it was storming and they announced when the last show would be and what was being cancelled due to the weather. I don't think they updated app but made announcements every 10 minutes it seemed park wide.
I got frustrated with Sea World because if you didn't pass by Journey to Atlantis to see the sign you didn't know, so then you went over there at 7 to find out then it was closed. They didn't have ride time closures in app. But based on what people are saying here, it is 20x better than Uni because I learned to ask team members when I wasn't sure and across the park.
Buy outs are known way in advance, there is no reason for those closures not being updated in the app and having signs up.
