I teach 73 students and I noticed that the choice of the pivot point from the top menu is unstable. What is selected is not always what is used by the transformers.
In such circumstances, the Pie Menu displays the real actual pivot point used. I’ve even seen two different active pivot point types in the Pie Menu.
The Pie Menu is reliable, it is always the pivot point used.
