I got a red popup and closed the site. What happens if I access it again?

Sentinel3 will show you a red popup every time you visit the site, preventing you from interacting with it.

If you want to stop seeing it, you need to add the site to your 'Allowed' list. You can do so by:

A) Clicking the link in the red popup to ignore it

B) Manually adding it to your exception list.
