App will not boot half the time and when it does there is major latency. You press a screen icon and seven seconds later it reacts. Unable to effect any changes in the programming remotely. Can't even turn it off or switch modes, it refuses to accept any changes. UPDATE: Have worked with the app to control floor heaters now for three years and during that time most bugs have been fixed. It has proven to be one of our better lifestyle apps. Wish it worked with Alexa though....
