My experience at Apple was that the developers didn't test situations with variable internet coverage, and didn't respond well to bug reports featuring such events. (At Apple, everyone is expected to use company-supplied devices running pre-release software and report any bugs encountered. This included using them in one's personal life; they actively encouraged installing games and other obviously non-work software.) So I took my company phone on vacation, and filed plenty of bugs, some of them about unwanted effects of driving in and out of cellular coverage areas. I've never worked for Google, so am unfamiliar with their internal attitudes, but generally it's tweedledum and tweedledee, including hiring from the same pool of developers. At a guess, a bunch of very urban youngsters don't believe in their guts that spotty internet coverage is a thing, except maybe in some third world dystopia. They probably do believe it's possible to have no internet coverage at all, but they simply don't think of intermittent coverage.
