alexa keeps sayin unresponsive

alexa keeps sayin unresponsive…
yeelignt v2 color x 8
servers tried Germany USA and Russia
ive updated lights to latest firmware

removed all yeelight skills, reloaded yeelight app but still no luck
also find yeelight app slow to respond

if i have one light added it seems to be ok (but slow) but if i add two or more then i start to have issues with alexa saying devise is unresponsive

yeelight app takes awhile to say light is on or off
