More a suggestion than a question.
Many people have had a problem when working with Courses via the Web app in a browser on a PC. The problem is that the map always starts up defaulted to Olathe, Kansas USA.
I eventually found a post on these forums which suggested I change the browser permissions for connect.garmin.com - allowing that website to access my PC's Location. I did this - and it now works as I would expect it to, starting up in the PC's location.
I made the change in Chrome on Windows, but would presume other browsers would behave similarly. Emphasising - this is a browser setting on your PC - not a setting wtihin the connect.garmin.com web app.
So suggestion - could this piece of info be added to the FAQ for the connect.garmin.com website, or otherwise publicised wider. A bunch of people have had the same problem, just search for "Olathe" to see quite a few.
