I’ve owned my Masterbuilt 1050 almost a month!  Many negative reviews complaining about the app and connectivity to grill was a concern!  I did have some trouble accomplishing both until I actually started the grill .  Meaning the fan was actually on!  At that point my app worked when before my phn was connected but I couldn’t access the app!  So far I’m more than satisfied with my purchase!  I hope this information helps other consumers be able to take advantage of this grills full features!
