I've integrated a Google Analytics tag to my InDesign Publish Online document following the steps detailed in the recent announcement / setup guide.

My analytics tag successfully identifies views when I load the document on the indd.adobe.com site, but it does not capture activity when I embed the InDesign viewer on a third-party website.

By using "Inspect" in Chrome, I can see that the INDD embed includes code that references the correct Google Tag on third-party sites, but Analytics isn't registering the view – even after I click "Accept" in the cookie banner, and after I allow third-party cookies in my browser.

I have added the relevant domains to the cross-domain configuration in Google Analytics' web stream details too, but that hasn't made any difference.

To reiterate, the tag works for the document when viewed on indd.adobe.com, but not on third party websites.

Any suggestions?
