Good day!

I'm testing the internal payment system for the application. Published the application as a beta version, organized a closed testing. Entered your mailbox (it is also fixed behind the phone). I got the link, I open the application link (at the same time I deleted the version from the phone that was installed). I click - install, and he writes me - "Another user has already installed an incompatible version of this application."

What other user? Why is it not compatible? Nothing is clear. If I download the signed apk directly and try to install it, it says - "Installation failed". If I run the program through Android Studio, then everything is ok. works. But payments do not pass.

What is the problem?

    Remove through adb uninstall . Also, if you wrote tests for the application, then delete them from the phone.

      There can be more than one user on the device. Quick access to changing users is available in the notification bar. Change user and remove the desired application.
