Google Docs thumbnails do not update, can I force an update?

Question

I am working with Google Docs. I make copies of existing documents using the option File - Make a copy.... The document gets copied and I work on the copy and change the copy. When I close it and reopen it the changes I made are applied but in the overview Docs Home the old preview stays.

When is this updated?

Is there an option to force an update?

Answer 1

Actually it's very simple. Here's the challenge the way I understand it. You've changed a document, most notably an image. The document updated great but the thumbnail still presents the old image.

Here's my way of fixing.

1. Make a copy of the document. You'll then see a second thumbnail appear but this time with the new image.
2. Delete the original document.
3. Rename the copy.

There you have it. An updated thumb.

Answer 2

Found another way to update that doesn't require re-authoring the document. If it's in your quick-access row, right click the old thumbnail, and click "Locate". This forced an update of the thumbnail for me.

Answer 3

You can delete the file, then click Undo, and it will generate a new thumbnail.

Answer 4

If the PDF preview of a link to GDrive in a document is not updating, you can fix it like @Drew by going to the list of documents and reopening the document.
