Doc preview can not change after published document?

Hi,

I changed the header after publishing, and republished. But preview still doesn’t change. Does the thumbnail already issued not change at all?

Thanks in advance.

Hello @1_24!
Are you talking about a template?

Or a published doc?

TEMPLATE
If you are talking about templates, the answer would be no. When you create a doc based on a template, what it basically does is making a copy of the template at that moment.
If you make changes to a template afterwards the doc won’t update because it is not linked.

PUBLISHED DOC
If you are talking about a published doc, the answer is yes! but you should know that the changes you make to the editable doc take a little while to show on the published link, sometimes a couple of minutes.

I hope this helps!
