The 'Web Browser' label isn't really accurate but nothing else was appropriate. I have Google Fiber and a Google modem/router and 3 2nd Gen Chromecasts in my small (1500 sqft) home. Two of the Chromecasts work fine, connecting to YouTube TV and allowing a show/movie to stream immediately. One of them is hit or miss.
What happens is that it is often being unable to connect (just a spinning circle) when actually trying to start a show in YouTube TV or Prime Video. I then have to restart or sometimes a complete removal from the Google Home app, factory reset, then adding to the Home once again...that USUALLY works but sometimes have to factory reset a second time the same evening. The Chromecast is plugged into a power strip and does NOT get power from the tv's usb port. The tv is an older LG but I wouldn't expect that to make any difference. I have tried swapping the Chromecast from one of the other tv's but it hasn't made any difference.
