"Application not installed"
So, it seems like maybe a third of the time, when I get a notification of an app needing an upgrade, I will go through the process and then get:
"Application not installed. An existing application package by the same name with a conflicting signature is already installed."
I could, I suppose, delete the app from my device and rerun the update ... except I don't know where to find the update file.
Any 'best practices' suggestions on updating apps?
