Old user interface but on the most recent versions of Oculus software/runtime.

So in version 19 it became possible to test out the new "advanced" UI from the experimental features in the Settings. Sometime during a version 20 patch, it appears that it was no longer an optional feature, but instead became the new UI. I have had some of my users contact me and when they explain their UI, it is the old UI; Upon asking them to navigate to settings and get them to read me their version numbers, everything is the same as mine but they do not have the new UI. In fact, when they navigate to experimental features, they don't even have the experimental feature options to use the new UI.

If anyone can assist me here, it would be very helpful.
