title: free and paid app signed one keystore
body: <p>I was sign 2 apps (free and paid) with one keystore but with different aliases and have the same versionName of free and paid app its 1.0 ofc. So, people who buy paid app cant install this paid app because they have free app on device. When they delete free app - instalation is good. The names of applications are different! Please help me understand what wrong? Thanks</p>
