Every time I think I have a understanding of how things work . Google changes the game that make you think that they want to see everybody jump through loops. I have to say one url maybe a good thing. If you don’t use tracking they will set it for you by the end of the year.
They say you can get help because upgrading like this is just like creating a new ad, it triggers a review and reset your performance and stats. Hopefully it will make easier to track your clicks .Just something to think on ,oh it don’t start until July. Have a great day.
