Dan,
Thanks for your response. We, the engineers, found the work around by uncheck and check the “Heatmap button”, then the heatmap will response to the frequencies button. The same with the “walls button”, the red walls always display even the “walls button” unchecks, but if you check and uncheck the button, the walls go away.
But for the managers; they don’t view the heatmap every day, so kind of awkward for them to see a product not working the way it should work. I ensure them Aruba probably will fix it at the next upgrade, but after two or three upgrades, I probably will open the ticket.
