It’s definitely still not consistent. We were there Thursday to Sunday this past week and I think it only opened at 9 two of those days. We got lucky and the day we picked was one of them! We lined up at the gate around 8:20–it was a busy day and the lines were long already. They opened the park about 8:45, and everyone was pretty courteous about speed walking and not pushing or running.
By the time we got scanned in and back to the line it was a few minutes to 9, and the app had switched from “opens at 9” to “delayed” so I thought we were going to be out of luck. But they were letting people line up, and the line was moving, so we jumped in. Right after 9 the app switched to showing 120 minutes.
The line mostly kept moving and we were off the ride a bit before 10, so not too bad. I do feel like they could have added a few more interesting bits to the queue given how long it is, but I imagine they’re assuming it will die down at some point. My 8 year old survived the wait without much complaint, which surprised me!
The next day it didn’t open until around lunchtime , and one day it didn’t open until close to 3 pm. Those delays then lead to inflated waits everywhere else...we were going to try for a second ride on hippogriff one of those days, but as soon as Hagrids was announced as closed that line jumped to about 90 minutes.
