Google Analytics has such shit documentations. They switched from some analytics.js to gtag.js, but didn't update everything in the docs, so I have to guess and find how to do things the new way. Also all the issues on StackOverflow are by marketing "specialists" who don't even understand JavaScript. And debugging any of this is near useless. You just send data into a magical data layer and hope Google does what you want. It's a fucking black-box and I've no idea why nothing works. FUCKING GOD DAMN PIECE OF SHIT, WOOOORK!
