I followed the steps to connect my Google Home to my TP Link devices but after I authorize TP Link in the Home AP I get a page that reads, "You haven't added any devices yet". When I tap on the plus sign it just goes back to the authorize page in and endless circle. Compared to connecting to Amazon Echo it's a nightmare.
