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?
