Hi

Hoping someone can help me i have a cloud gate way fibre then a Flex 2.5g and three APs, was set up by a friend and all was working great , but i have just added a USW Pro max 16POE , i just connected everthing that was connected to the Flex into the USW and then unplugged the flex, all is well apart from that Apple homekit is showing as more than half the devices as updating have checked all the settings on the new switch are same as old but a newbie so not really sure what to do thanks
