Which Android versions is Titan remote app v12 compatible ?
Works on Android v9 with emulator terminal, but I can't install this app on Android v8.1
HW for Remote Titan is an Android v8.1 tablet, so the only option is to replace HW to work v12 app on Titan One v12 ?

And they do not know what port to allow ? Shutting down the firewall is not a happy idea.
