Dang it! Thought I may have stumbled onto a fix for more than just me!
For what it's worth, I've been cell service shopping lately. I've trialed Cricket, Mint, and now Visible. On all of the data services, the live video issue persisted. During that time, I changed from the Pixel 4XL to 6. Neither phone showed live data regardless of cell/wifi. My only success came with disabling the VPN (or using my iPad)
