Got someone else's QR code for the APK generated

I am testing my extension from the morning like compiling over 3 APK per half-hour from time to time...

I compiled my APK and installed it, but it wasn't mine:

This is not the expected result... Talking that this happened rarely but it's very dangerous to expose other APKs.

The QR result generated here is not mine or it's wrong.

and the url as well ?

Yes, as well as the URL. I checked it with my two devices...
