Fullscreen does not work

I installed and connected OptinMonster successfully and started creating my first fullscreen campaign. I just designed the Yes/No layout with a button linking to our email, then set it to close the campaign.

My display rules are:

If
– Time on page is immediate
And
– Current URL path is any page
Then
– Show the campaign view: Yes/No

I cleared my browser cache, but the campaign still doesn’t appear.
What can I do?

The page I need help with: [log in to see the link]
