Google pub/sub slow? Nest thermostat responses

Has anyone else started having issues with responses being really slow back from Google Nest thermostat? It seems to be evening time UK. I can send commands to change temperature which are quick but if I change the target temp on device the response back to HA is really slow to show it’s changed to heating. If I set temperature on device or my nest app it’s instant but HA really slow to update on dashboard. Recreated pub/sub but same.
