Unfortunately my new phone (Galaxy S8+) automatically downloaded Aquamail 1.9.1.360 before I could set it to only download apps manually.
I am trying to install 1.9.0.320-dev, but I get an error message:
App not installed
This package appears to be corrupt
I've downloaded it again, but always get the same error. Any ideas as to how I can install it? Do I need to uninstall 1.9.1.360 first, and if I do so will I need to reconfigure all my settings and widgets?
