Automatically logged me out due to a server upgrade effective 14 March 2022. Took an hour and a phone call to HP support to realise I was struggling to log back in because the app appends a superfluous space to the end of your username. Total inefficiency from HP. I don't need an app to operate my vacuum cleaner so why do I need one for my scanner? I notice support isn't even free outside of warranty period, when it's bad app design that caused the issue in the first place. Shabby all round, HP.
