setting zones on computer

As recently as a year ago (I think), I was able to reset and adjust my HR and power zones for the Garmin 540 while signed in to my Garmin account on my computer. I find the app on my phone cumbersome for such things. Apparently this feature is no longer possible on a computer. 

On my computer, I would go to upper right of screen to the image that looks like a watch, select Edge 540, and then go to "device settings." The actual words 'device settings' are still there but are no longer a link to be able to set zones (it does not open anything, cursor does not activate or 'light up'). 

Anyone know why this no longer works and/or know of a fix? Garmin has not responded, which I am finding more and more typical....    Disappointed
