I have this issue too: I don’t want to sign in to Google and do not want to be forced to. But every few times I turn my Aura on it tells me I have not finished setting up the device and then takes an age to respond normally, or needs a restart, if I persist.
I’ve set it up to go straight to a channel of my choice without any faffing about and that’s my choice. I assume there’s no way I can tell it I simply don’t want to sign in to Google, once and for all, or is there?
