Horrible app. Won't let my account sync or sign up for Instant Ink. Super slow when trying to do anything. Although I can print, I can't actually do any of the other things it gives me the option for in the app. Waste of time. Been trying to set up Instant Ink for months but it keeps getting me to the last stage and then "there's something wrong" but nothing that I have done is wrong so you need to sort it out.
