30 Second Page Load Caused by Google Tag Manager

Hey!

I was super confused why my website is taking 25-30 seconds to fully load and why all of the animations and interactions are slow and choppy.
After some website speed analysis I saw that the Google Tag Manager is causing huge website slowdowns. I removed GTM and my website all of sudden works perfectly, it loads in 2 seconds and all of the interactions are smooth.

I would love to know if the issue comes from Webflow or from Google’s part


Here is the published test page with GTM so you can see the load time and how animations play out.
