Similar problem with the Dyson 360 Eye connection with MyDyson app failed but its for the Dyson Purifier Hot+Cool Formaldehyde purifying fan heater (Nickel/Gold)
I’ve moved the device til its almost sitting on the modem and no I’ve not reset the modem as its working just fine for every other device including the apps on my phone.
Slow connection speed?? I think not baby puppy
