The same document when I open from browser download its updating.
when I navigate to downloads and try to open the same file the page number is showing 4 in first page.

I have done all the options which you have mentioned, but still i am not able to find out the root cause or workaround.

Also other members in my team also facing the same issue, if my word is having problem then the issue is specific to my word, but everybody is facing the same issue
