I have had my Nest for some time now and other than this issue, which
did resolve and has not reoccurred, have never had any issues. The
system has done a good job for us.
Am having same issue. Thermostat shows online and apps on iPhone and
iPad are both showing offline. Everything is working except the app on
my devices. There is no router, battery or other issue covered in the
support documentation. Google team pleas...
