Finding the tracking id
This is where all the PROblems start...
Unfortunately, i could not find it, there are a lot of sites stating that you have to go to your property section in that admin menu (blue circle with a gear) and there you can find somehow the tracking id.
It can't be the Google Tag id and i will explain why i think so. Easy. Google tag works when you insert some js code in your page but we cant do that in GitBook, unless this is what the Google Analytics integration kind of does.
So, that thought made me realize that i was wrong. I checked the source code of the page and this is what i have found under the head section
src="https://www.googletagmanager.com/gtag/js?id=[and there the gtag id]
So the mistery is solved, just copy your g-tag id and paste it in that damn field. G- should be also copied. I guess it is just the matter of time untill it will start working, so wait.
