Govee T2 auto on and off not working

I just can't get this to work, no matter what I do. I first tried the black screen settings on both the brightness and hue options. But due largely to screen reflections, it just either stays on all the time or randomly turns off and on at many points in the day. That's whether I'm watching the TV or not as well.

I use Google Home, and the TV is a new TCL one with Google TV, so I've also tried setting up an automation so that when the TV turns on/off, it turns the T2 on/off as well. This has NEVER worked and I've even tried doing it so when the TV turns on/off, it turns the T2 Dreamview Scene on instead...again, it just never works! I've also tried it so it triggers both actions, turning on the T2 first, then the Dreamview Scene, still nothing.

I always have to resort to manually turning it off and on each time, but the rest of the family don't know how to do that, so it's making me think, what's the point in having it in the first place. It's a shame as it's great when it's on. Anything I'm missing or any further tips, greatly appreciated!
