Devices not responding since HomePod mini 14.4 update

I updated my HomePod Mini to 14.4 earlier this week and now my lights (Vocolink and Meross) and my Eufy camera keep on going into a state of Not responding. Powering them off and back on again resolves it for a short period but soon after they stop responding again. Reset the HomePod and reset and added all the devices again but they still keep going into a state of not responding. All were working fine for months before the 14.4 update. Any ideas or help would be greatly appreciated.
