Not come across this before and unable to test as the older version of tableau and would probably depend on the tableau server
Is the second sheet already scrolled down when published.
Thats the only thing i can think of that may be the problem.
Double check this.
Also if you can help by sharing some screen shots of the actions and the sheets in question. this would help navigate the issue.
Both Dashboards are set to "Automatic", so no, no scrolling on the Dashboards or Sheets are possible.
What is strange that this does happen only when I publish... desktop preview works fine, as expected.
I am having the same exact issue - did you ever find a solution? My temporary fix is to place an image of an upward-pointing arrow on the dashboard, so my users know to scroll up to see the content, but this is not ideal.
