Without going into too many details, I found the OP's use of anti-adblock on his site a turn off. But I needed a ROM for my Pixel 2 XL as my roommate will be using it once my Pixel 6 arrives, so I bit the bullet here.
Anyway, I was surprised at the use of Camera Go, as compared to the full app it's very limited. I found I couldn't set a viewfinder grid - which I use - nor could I set the camera to work in 16:9. So I searched and used a modded Google Camera app from XDA:

Despite its size (270MB), it works perfectly, and so I disabled Camera Go. The only thing I noticed is that the ROM reports itself as a Pixel 6, and I'm wondering if the Google Camera issues mentioned are a result of that.
