I'm having the same problems with my Ironwood 650, which I bought on Saturday, April 6 and seasoned yesterday, April 7. The QR code isn't working on my Android (Samsung Galaxy S9) phone. For some reason, when I get to the "Home Wifi" screen on the Traeger app the first sentence on that screen "Your grill will be connected to" doesn't populate my home's wifi network. Therefore, the sentence reads "Your grill will be connected to." I've tried both the QR code and entering the information manually and neither method works. Additionally, I tried smoking some beef yesterday at 225 and the temperature never got past 205 (ambient air temperature was 65-70 degrees). When I cranked up the heat to 235 or 250, the grill warmed up and either exceeded those temperatures or stayed fairly consistent. Looks like I'll have to call Traeger to discuss both issues, which is disappointing based on the price of the grill and based on the fact that the main reason I upgraded was to achieve and maintain consistent cooking temperatures. I was expecting this product to work correctly right out of the box.
