got iPadOS 15, but when I go to ‘about’ I still see ‘iPadOS 14.7.1.

Furthermore, everything is the same, I can’t place widgets on the Home Screen, e.t.c. I’m sure I properly installed the ipados 15 profile, by downloading it then hitting “install.” Then it prompted me to restart my device, which I did, and apparently I was on ipados 15 public beta 4. But everything is still the same as it was in iPados 14. Why? Did I do something wrong?
