The default configuration of the YouTube video widget does not enable tracking of views without forcing all videos to reload via a JavaScript API triggered in GTM.
This effectively means we can choose either:
1) Tracking video views but degrading customer experience and performance due to the flicker and reload
2) Having no flicker and standard load times but no tracking of video views.
I would be great if this was solved by the webflow team for non-developers. I've given more details here:
