We have a noted a serious drop in performance embedding PlayCanvas builds with an iFrame. Loading times are taking extremely long or failing all together, typically causing the browser to show the page is unresponsive dialog. This is not a problem on mobile, seemingly only on desktop. Edge, Safari, Firefox, and Brave, all perform fine.
Any ideas about what this could be? Completely stumped at the moment.
Following up on this. The same issue is occurring opening the editor, constantly waiting for it to load, seeing the unresponsive dialog, clicking and wait, and repeats. Sometimes it finally loads, often not. Completely fine in Edge and Firefox. Happens even on a brand new project.
Tried this in incognito mode and with every extension turned off (running very few to begin with), neither makes a difference.
Need some urgent guidance on how to debug / resolve this. Thanks.
