Man I tried everything on this page and I still get the dreaded need software update but then there’s no update. I have a series 2 Nike watch and iPhone 12 running 14.6.
rebooted both devices, changed network to 2.4, reset settings, wiped watch clean, paired in all the different ways, removed all other Bluetooth devices from my phone…. Nothing is works. Even went and tried on wife’s iPhone 6+ and got same problem.
