The first message has been reported, but might not get fixed any time soon. We completely understand why it happens, and we know that the result is not causing any problems.

The second error message is when the visitor has an active session happening (based on cookies), but for some reason the browser has changed (based on the reported "user agent string" - typically a browser version upgrade). Or, maybe in a couple of cases, when the IP address has changed - though when the visitor is meandering among numerous wi-fi hotspots, the IP address may change frequently, so aborting a session because of this doesn't happen that often.

In the above message, the session switched from "Android 7.1.1" to "X11". Perhaps someone was testing the site by having the browser simulate a mobile device.

On your tablet -- and you can make your tablet's browser pretend to be any one of several devices?
