Hustle's Hubspot integration is not working

Hi, I’m trying to use Hustle with Hubspot integration however when I click the link to connect the two for oauth it refreshes the page then just remains the same so it doesn’t fetch any lists and form entries don’t end up properly on hubspot.

They just deprecated some functionality at the beginning of the month, not sure if this could be related since it was previously working: https://knowledge.hubspot.com/articles/kcs_article/integrations/how-can-i-install-the-hubspot-tracking-code-for-wordpress
