Looks like you get this useless message automatically via SMS when entering Switzerland. It applies to no-one right now as no countries are on that list.
@pete switzerland has been chill, pretty sure they were one of the first places to start opening up
@pete their "test to release" quarantine stuff was a bit whacky though, could test to release but not use that same test to go to large events
Arrivals at Zurich airport does however have this going for it.
