I have seen posts on this problem a few times but not on Android ( only iOS). I've tried three phones so I don't think it's a phone thing.
When I try to link my energenie app with nest it opens the nest app and says "Cookies are blocked. To continue allow third party cookies in your browser."
Cookies are enabled in the browsers on all the phones I have tried. I have tried deleting and installing different browsers with the same result.
Any help would be appreciated.
