Just got 3 of these to broadcast in a store but when i make the account it brings me to an screen that says “sonos found on this network” with buttons that say update and more options. when i click update, it tells me sign in to get more features. It tells me enter the account information for an email that i don’t recognize and neither does anyone else here. no one has used this email. it blurs out the middle letters so i can’t email them to find out what it is. i tried putting in the email i used to make the account instead of the one it’s giving me but it won’t work. Please help.
