Integrating Pagesense Snippet using GTM: question on tag firing options

Hello,

I'm integrating Pagesens on my website using Google Tag Manager.

On GTM every tag as several "Tag firing options":

Unlimited
Once per event -> Fires every time there's an event (i.e. click on a link, page load, form submission)
Once per page -> Fires only once when page is loaded

What is the correct option to use? Is firing the snippet once per page enough?

Thank you

CSS not loading in heat map view
I ran into a problem with two different websites where when I view the heat map experiment, the CSS for the page is not loaded under the heat map overlay. When going to the page directly, everything looks fine. The page also looks right on the Experiments page where a screenshot is used as the thumbnail... The sites are both WordPress websites. I've tried both the regular snippet and async. I'm hoping this has been seen before and there's a solution. Thanks!
