Why does this app suddenly have to reconnect all the time. Been a user for a few years and generally happy but with the recent update I felt compelled to update my review. The app now spends ages reconnecting every time I switch to it, even after a few minutes. Once connected commands take several seconds to execute. Hue Smart Button responds crisply so this has nothing to the Hub or network. This app update has changed me from a fan to now looking for other solutions.
