Right now, the Google Ads tracking template isn't working, but they're trying to get it officially recognized. For now, you should avoid adding the url template to your Google Ad account because it will cause your ads to get rejected right away. If that happens, you'll have to go through an appeal process to get your ads back up.

However, the good news is that the new tracker they've introduced seems to be working well and doing its job. I really like how the system puts together a Refund Claim for requesting credit from bad ad clicks.
