Thanks for posting to PX Community @Alistair FIeld !
The “Bookmarks” button is only available within Audience Explorer and as a dropdown option on the newer Accounts Explorer page. All other reports have a “Save As” or “Save” (already saved) button, which makes those available for easy access in the My Reports section inside PX.
Please provide a screenshot from our documentation where you identified, “I do not see it on the report next to Export like it used to be as per the documentation.”, so we can ask our docs team to update this quickly.
To your last point, I agree that some of the PX product screenshots are out of date with the many UX and PX Feature updates/improvements that our PX Product team has delivered. Feedback such as this will help those teams to update those assets as needed. It is a big job with so much documentation covering many different Gainsight solutions.😅
Happy PX-ing!
