If you’re seeing a never-ending loading animation when you edit a blog post or landing page, you’re not the only one. The solutions for this problem is fairly simple: enable third-party cookies.

If you don’t want to enable all third-party cookies, Chrome also allows you to select the specific third-party cookies required for HubSpot:

4. Select each blocked group and click “Allow”.
Once you're done, click "Close" and reload the page. You should be able to edit your content now.
