Appreciate any insight anyone can offer as this is driving me absolutely insane. My home setup consists of:

• 7x C by GE Cync bulbs connected to the C-Reach Hub. For HomeKit these are added directly to the Home App and for Google Home they are through “Works with Google” by linking to the Cync App.
• Various Nest Devices all added directly to Google Home app and to HomeKit via Starling Home Hub
• 2x Kasa Light Dimmers added through “works with Google” by linking to Kasa app and to HomeKit through Hoobs.

About a month ago, after adding the 7th C by GE bulb, all of my devices essentially became unusable via Google Assistant voice commands with repeated, “Sorry it looks like [device name] isn’t available right now” prompts. They are all 100% useable without any errors in the HomeKit app and they respond about 90% of the time via the Google Home app. I have done the following troubleshooting steps and the GE bulbs still have extremely intermittent usability with voice commands - which is what my wife relies on 90% of the time.

• Manually reset all GE bulbs to factory settings and relinked via Cync app
• Nuclear option by actually deleting my entire “Home” on Google Home and the HomeKit app and started fresh (was thinking there might be some phantom data out there causing issuse).
• “Hey Google, sync my devices” - constantly to ensure they’re alive

Nothing has seemed to help. Any ideas as to what may be the cause here? I am awfully close to just throwing the GE line of bulbs away and starting fresh with Hue. I realize that Hue is a better product line but I would also hate to be wasteful just to throw what were perfectly useable (1 month ago) GE lights away.
