A:Answer I can give you a generic answer, here, from the perspective of a very long-time user of computers, software, and apps. Unless the upgrade is because of a serious security vulnerability, avoid installing it until you stop reading new complaints. Upgrades are notorious for being released quickly, without proper vetting; and only after end users start yelling do the code writers get around to shaking out the bugs. As far as I know, my Nest app has gotten no upgrades, and it's working fine. The old adage, "If it ain't broke, don't fix it" applies here.
