I spent 1.5 hrs on phone this week to support and learned that you can decrease font size on your MYOB by using Control and - together (increase with control and +). Maybe you all knew this but I couldn't do this by using my fingers on the screen as usually works with other apps.
Yes the font is smaller but you can actually get a decent few invoices to fit on the active part of the screen then. A second pop up occurred this week and I blew my stack because I could barely see 2 invoices and scrolling was a nightmare. Hope this helps someone.
