PDF download options missing or causing errors in dashboards

You may experience issues with PDF export options in dashboards, which can impact your ability to export reports as intended.

The following options are missing from the Download as > PDF dropdown or may cause errors when selected:
  • Current sheet
  • One sheet per page
  • One visual per page on current sheet

When these options do appear (for example, in the app or email export modal), selecting One sheet per page or One visual per page on current sheet may result in an error. Due to these issues, the system defaults to exporting only the current sheet as a PDF, without the ability to change the setting.
