FWIW, I tried the first query on Google Home and it suggested I talk to a third party extension called "Air Check." I didn't go through with connecting it but I assume it would give you what you wanted. It sounds like you were on mobile so maybe it's different there. I actually appreciate it prompting to connect before making the request because there's probably some privacy tradeoff there.

The second query was hard for me to test but it seems like a reasonable one to make.

The third one is probably impossible due to Instagram's TOS (among other things.) Their TOS states: "You must not crawl, scrape, or otherwise cache any content from Instagram including but not limited to user profiles and photos." [0] After Cambridge Analytica I'm not surprised that this is the case. Even if Instagram allowed scraping of their data, this feels like a somewhat specialized (though currently very relevant) request. I tried reformulating this request as "What is the mask compliance rate in Shasta county?" which also didn't turn up results, but I'm not surprised by that either. I suspect that data doesn't exist anywhere, so it's hard to fault the assistant for not pulling it up.
