Hello, I used Microsoft's "Preparing an Application for Release" and "Signing the Android Application Package" tutorials in order to run an APK of an app I built on my Samsung Galaxy S8 phone.
When I try to run the APK, I am getting a message "Do you want to install an update to this existing application?...", and when tap "install", it shows an "installing" screen, and after couple of seconds I am getting a message "App not installed".
I have done these steps couple of times, each time I got the same result.
I disabled "Play Protect" and "App Permissions", tried creating different key, removed all previous distributions (same project, none of them worked).
I am using Windows 10.
I would like to know what could probably fix this issue?
