Please add me to the list of people asking for the PO line to be reinstated on the mobile app.  And could you also put me in for having the option to print estimates from the mobile app to be reinstated as well?  There is no longer an option to do so, and I haven't been able to find a workaround.  These updates have my contractor client extremely frustrated--an understatement.  Things he used to be able to do quickly and easily have become a nightmare for him.  We also had trouble with sales tax, but I'm hoping we have that fixed.
