My Series 2 watch has been rebooting at random ever since I installed watchOS 4.2. It reboots several times per hour, rendering it nearly useless. The watch operated perfectly with watchOS 4.0. I have erased all content and settings several times, removed all third-party apps, and set it up as a new watch, yet the problem persists. Apple ran a remote diagnostic on it Saturday afternoon, but they said the diagnostic didn't find any issues. They think it's a hardware issue and they want me to send it in, but it's out of warranty. I'm having a hard time believing it's a hardware issue because the watch operated normally with 4.0. Is anybody else experiencing this? Any help would be appreciated.
