Unable to accept license term in photon chat filter

I want to user photon chat filters. For now I am in free tier.

when I press "Agree" in the "Acceptance of photon license terms" page, It redirects me to a page Saying

"Sorry, apparently we have a broken part in our page.

An e-mail has just been sent to the person who can fix this and it should be corrected shortly.

Try browsing our homepage meanwhile."

In this condition, Is there a way to use photon chat filter service?
