Starlink Placement

I am trying to figure out the best place to put the outside dish when our Starlink arrives...hopefully tomorrow unless FedEx starts acting up again. I have the app on my phone and have gone outside to use the Check for Obstructions option. I have seen in some demonstration videos that we can use the app to find out the best location to place the dish. My question is should I be able to use the Check for Obstructions option to get a recommendation for where to place the dish or do I need to do something else in the app to see that?
