This happened in the previous build. Downloaded V12.6 build 448 and still have this issue.

On a folder search (with subfolder option) The results come up but I get the error: The text in the document may have changed since the search was performed. (doesn't matter if no pages are opened before the search or if a few are opened prior to the search).

Clicking on one of the results nets the same error!

I can manually open the page and do a search (on current document and find the result).

This new build did not fix this issue. Yes, I reopened my old support ticket. (need to add photo though)

Hope the pic goes through this time.
