Also experienced issues with HomeKit - Philip’s (terrible IMO) latest update to the Hue app killed the iOS widgets feature and makes you use Shortcuts instead, which uses HomeKit. I found lights frequently would not respond via Shortcuts/the widget that worked fine via the Hue app. I ended up buying the iConnectHue app which has a native widget and works perfectly. Not sure what the difference between HomeKit and Hue protocol is in this scenario but it was definitely causing regular issues.
