INFURIATING! I have an Echo Dot and Android App. Alexa does not control my smart lights well at all: several will not turn off/on or change brightness/color with the rest of the group, BUT IT IS DIFFERENT BULBS EACH TIME! Alexa just can't seem to control more than 2 at any given time. PLUS when I've tried to delete the devices and start over it keeps repopulating the device list with all of the smart bulbs I've ever owned in my whole life. I delete them again, Alexa brings them back.😩
