I'm not surprised. There is no reason for that to work seeing it's a Google network/radio issue not a sim manager app issue. I'm always leery trying those homemade fixes that someone tried out on a friends phone. Also I don't believe it's the December update since it was happening on the November update as well, at least for me. The Verizon update page doesn't even have the Dec patch listed. I wonder if any carrier has jumped on the bandwagon or they held off, which is why no one is getting an OTA on Vzw or Att from what I can tell.

Both me and my wife have Pixel 6, same operator. I stupidly sideloaded the A1 OTA (well you know, I have the flashing fever

No to be full of sh##, I decided to took a picture of both phones, side by side. Left one is mine, on dec update.
