As of October 15th, my ecobee3 lite thermostat has been put into service, & remains so. There's been a couple of Android OS based app updates released since my initial install. However, something that has not yet been corrected within the app's setup process is the section labeled "Select your utility provider". I continue to return to this uncompleted step, each time encountering the message of "An unexpected error has occurred", "Please try again.". This error still exists as of 2/14/22. :(
