Sign In with Apple.... where is it? – Wynd Air Tracker and Purifier Review

I’m only going to purchase a unit once they add the ability to Sign In with Apple. Update: still no Sign In with Apple, and after 1 month of usage my purifier is completely dead. It will not charge. I have tried using multiple cables and chargers to no avail. What a expensive mistake this was.
