Every day I meet my students have trouble connecting these two services Google. The truth is that most of Google Analytics features are very well explained, but instead activating this connection it is not.
So to facilitate the work, here's this video that explained the advantages of having this connection and how we do it.
I am responding to questions through 3isic Youtube channel, The Research Institute that I have the pleasure of directing, but if you have any questions in particular can also raise it through a comment on this blog post and will look to answer you as soon as possible.
I hope you find it useful.
A big hug.
