Pixel 2 No Service on Fi with 22.2 nightly

I installed the latest avaible Linage OS (22.2 nightly) on the pixel 2 and I could not get Fi to connect to the towers. WiFi calling and text was fine no data or call via cell. I ended up reflashing latest stock from Google. Any ideas why I had to do that to get service? I read about and did the update / enable carrier services and called Google no joy.
