I am certainly finding MobileSheets confusing. I have read chunks of the full manual and it is still confusing.
I had not noticed that I had turned on performance mode at one point and could not work out why much of the UI was missing. It took me an hour to work out that it was performance mode but even then after turning off performance mode I had to exit the score view and go back in.
I am sure I will get there, but the UI is way less obvious to navigate than forScore’s was. I am still glad not to be paying a yearly subscription just to get access to facial recognition.
