Apk package not valid?

1

I can no longer install a native app (.apk) on my Android tablet: “Invalid package.” This morning, the same app was still installable. It is installable on my phone with One UI version 6.1, the tablet has One UI version 6.1.1, With the chrome debugger (F6) the app runs without any problem.

Try deleting the old app from the phone first - this has worked for me.

Thanks, this worked for me too
