I'm not sure if this is a question, a fact, or a warning to others looking to buy ads for their game. Maybe all 3. But I wanted to post to confirm it one way or the other. In the last step of the next-to-last step of the advertiser getting started instructions, there's a section about Tracking Links, which seem to be a requirement for running a campaign. And Tracking Links require implementing a 3rd party plugin of some sort. And the first suggested 3rd party link I tried was broken. Why can't Unity Ads provide a tracking link natively? Why can't this requirement be posted at the beginning rather than buried at the end of the implementation guide?
