I have one from yesterday where I tried to figure out if I could connect Files on my iOS to a webdav server.
According to Google that seemed possible.
While I don't use Google much more (except the last few days to figure out if the improved quality I've seen and heard about is true) I have enough experience from the last decade to not immediately believe them.
In reality, Roku uses a similar and half-compatible implementation of the Chromecast standard, but it isn't supported in all the same places you can Chromecast, and you'll frequently experience hiccups like the Roku only streaming in SD or 720p instead of 1080p or 4k.
This is partially the fault of the site sharing this information, as they're not presenting this in the most clear way either. However, when Google chooses to try to automatically answer my question, they become responsible for that answer, and when that answer is misleading, it annoys me.
