DaVinci Resolve Studio 17.1

Hello!
Need some help with optimised media.
When I right click a clip (for which I know there is optimised media) I do not see "Rediscover optimised Media" in the contextual menu. Also, in the Media Pool, if I right click one of the column headings, I do not see optimised media check box in the list.
Also, To clear optimised media: When I open the project, and choose Playback > , there is no "Delete Optimised Media" in the menu.
Is there something wrong with my settings? Am I missing something?
Please help.

I am running the Davinci Resolve Studio version 17.1
System iMacPro
OS: macOS Big Sur 11.1

Things changed on this front in version 17. The New Features Guide has more info on p. 17.

Thank you very much Jim, appreciate your reply.
Just saw it on page 17!
I misplaced my copy of the New Features Guide.
I do wish the updated reference manual is available soon.

Thank you once again.

I'm really hoping the new 17-specific training materials drop while I'm still in "shut down" mode. Now's the time to be working through those.
