URL Generator not tracking in "Campaigns"
I've created trackable links using the Google URL generator -- I've shared these links across several platforms and promoters: i.e. social media campaigns, blog posts, emails, etc.
I've noticed that the last several are not showing up in my Acquisition > Campaigns. I even created brand new ones to double check and clicked on live ones to ensure that they were getting some engagement. Shouldn't the ones that aren't even receiving engagement appear as "0" Sessions.
Help! I'm a struggling Analytics beginner.
