Thanks for the response @pford !
That’s interesting to hear because I thought the subdomain forward was what told Google to pick up the “app” part of the URL since the URL i purchased is only “www.batonreturns.com” (ie. not “app.batonreturns.com”)
On your second point, I orginally only had “app” under CNAME records, but it was not working so I added the second CNAME with www.app.batonreturns.com.
Not sure if you have any other suggestions since I’ve already tried what you said?
