I’m afraid there’s little you can do as a user.
Athom should solve these quirks. Do note Homey never has been able to switch more than X devices at a time. Apps like Device Capabilities and < Group > use a reliable method (sequential controlling) for that.
Probably Moods with just 2 or 3 lights work a lot better / snappier, you can give that a try.
I would discuss this with Support, Moods is not yet a finished “plugin” if you ask me.
