App doesn't update

I am looking at your solution at How do you change Package name any solution in 2021? - #23 by Anke

If that method is used then I must use it with every change of my app? Each time I make a change I must compile and then perform that method?

I saved my aia multiple times over a period of time as I made improvements and corrections. With major improvements I gave it a new name HRMHR1, 1a, etc. The last was HRMHR2c at wich point I saved it as the original HRMHR. I then restarted by loading it as a new project and yes I set project properties to HRMHR
