When an Android VPN APK cannot update the installed app

Troubleshooting steps

1. Check the installed version in Android app info. Identify whether it came from Google Play, the official site or your organization, then check for updates through that channel.
2. An in-place update requires the same application ID and compatible signing. If Android reports a package conflict, give the publisher the error and version numbers and avoid testing APKs from unknown sources.

How to choose the next step

If you must switch channels, confirm you can sign in again and back up settings using the app’s supported options. Uninstalling may remove local settings, so confirm how to restore them first.
