Controlling Nest thermostats is painfully slow

I’m aware that Google has screwed us somehow, but I’m not exactly sure what they did. All I know is that I’ve still been able to use HA to control my thermostats. I’m assuming I got grandfathered in somehow.

That said, after upgrading to 0.110.0 today, controlling my thermostats from the UI has been erratic and slow at best, to completely unresponsive at the worst. Is this related to the upgrade, or something else?
