I had a reply from the "google nest customer care team" they asked me to
update my iphone to the latest 15.3.... i did this and for 3 days now it
has been fine. I will continue to monitor it on a daily basis
I can relate to all of the above, having the same issues, been onto
Google nest support and they have taken me through various steps to try
fix it. Still no luck. Im finding the home/away very temperamental.
Sometimes it works . sometimes is doesn't....
