Hi @Pearce Galliher
The 'Highlights' dropdown in the revision history comparison view might be a bit misleading - it doesn't switch highlighting on or off.
Rather, it allows you to customize which types of changes are highlighted, like additions or edits, making it easier to zero in on specific changes.
Also, one more point is - Edit and share permissions shouldn't affect the visibility of revision history highlights. As long as your colleague has access to the document, they should see the highlighted changes.
If incase your colleague requires more granular control over change visibility, they can utilize the detailed list of differences displayed alongside the highlighted versions in the revision history. This list details specific changes made to objects within the document.
Hope this helps - Happy to help further!!
Thank you very much and have a great one!
Warm regards
