Hi,
Can you share a copy of your project with us? We'll check the cause of this issue to help you.
Use the "Create a backup in a ZIP" command from the main menu > File menu to create a full copy of the project with all linked files.
P.S. Jill, thanks for your replies!
Are you waiting for Publish to finish before checking?
You will get a green Tick when it is done. It can take a while to finish.
Also make sure nothing else is running on your computer while you do the Publish.
If using a laptop, make sure it is plugged in & not running on battery - it will complete faster when on mains power.
Jill
