Google Tag Manager causes lag in page loading

Question

There is a 5 second or so after the page is loaded, that e.g. clicking or hovering on elements won't work.

I figured out, it has to do with the Tag Manager.

Just like suggested in the guide, it's loading asynchronously.

Does somebody have any suggestion how to avoid this lag?

Answer 1

I found out what the problem was that was issue in our implementation, not in GTM.
