I wonder how well this works when using using wifi on and accessing a corporate intranet. I discovered https://myhrportal didn't work when I pinned my DNS to 8.8.8.8.
I didn't think it would work. From my own experiences...
One day when away from the office, I pinned my wifi DNS settings to 8.8.8.8 just to try it out & compare it to the DNS I normally use at home, but then I forgot to undo it. When I got back to the office, the office Intranet was unsurprisingly inaccessible, and I removed the pinned DNS settings. I knew how to solve the problem, but less savvy folks trying out the Cloudflare product might not, which could create some confusion for IT helpdesks.
Cloudflare is concerned with the user experience of people who don't know what a VPN is, and that's why I mentioned it. Normally I would have just tried it & reported the edge case I it exists, but the app isn't usable yet, so I posed the question instead. Judging by the downvotes, I should have mentioned that in my comment above :)
