Apple Watch users working in intensive care units are reporting Apple Watch problems, 9to5Mac reports. One user with an Apple Watch Series 3 was experiencing reboots every 60-90 minutes while working in the ICU, and the issue continued even after the device was replaced, leading to speculation that ICU-related equipment is causing the problems. The problem has become so pervasive that there’s now a three-page support thread for the issue, but the only proposed solution so far is to run the device in airplane mode — which negates much of its usefulness. The issue hadn’t manifested itself in the Apple Watch before the Series 3, but Series 3 devices both with and without cellular service have been affected.
