One of my devices has found its way back online spontaneously. I hope
this means Google has fixed whatever and the devices will self-resolve.
i wouldn’t remove any devices from an acct.
I don't htink it has anything to do with the app version. my devices are
showing the yellow circle at night, which should have nothing to do with
the app I think.
Mine have been dropping steadily. No networking changes, no
configuration changes. 4 out of 5 of mine are now down. Everything has
been working fine for many years now with no issues. The WiFi still has
2.4g enabled and working for other devices.
