Hustle ActiveCampaign broke after Update

After I updated to latest Hustle 3.0.7 on one of my sites the terms and conditions checkbox no longer worked.

Even when I checked the box, it still said I need to accept the terms and wouldn’t let anyone submit.

Please note, the above link is working now as we rolled back to version 3.0.6.1 and the plugin then worked ok again, so the issue is something that changed in 3.0.7 somewhere.
