Setting up goigle analytics and Google property id

I was trying to set up Google analytics and I can’t seem to do that. It looks like it’s using the old system. Are there any plans to update?

My other problem is that I’m not sure hiw to set up a Google property id ss I can’t find the header and the HTML & CSS header section doesn’t work.

Hi!
There is a specific field for the property ID in the marketing section of your settings. There is no need to add it to the header manually.
