Hello, thank you for the reply.

I think there has been a bit of confusion, i know the steps to install an APK, but the confusion is over how you installed an android 10 + version of the ebay APK on your android 9 device, attempting to do so would usually result in an app not installed error due to code version mismatches with the installation process, or the file not being readable at all, did you force install using the normal apk installer, or a commandline such as ADB (Android debug bridge?) kind regards.
