Office 2021 LTSC: Visual Refresh, Focus-Mode, Draw Tab; Safe-Mode

Although I had access to them in my personal Office 2021, my Office 2021 LTSC seems not to have the "visual refresh," the focus-mode, or the draw tab (I am not using a stylus). Oddly, however, all three of these are present if I run LTSC in safe-mode.

Any ideas? Thank you.

The Microsoft Office LTSC Versions don't get all the same updates that non-LTSC versions get. Guarantees of longterm stability without the impact of regular feature changes is intended to be one of the benefits for organisations. See Overview of Office LTSC 2021 - Deploy Office

'Major' feature changes only come with a new version LTSC Version installation/upgrade and that decision is with organisations.
