I only see stuff for Android 6:

Was Android 9 a beta release? I don't know.
Two things to try:
Give me the fingerprint of your current release. It should start "Onyx/NotePro/NotePro:9..."
You can use "adb shell" and "getprop | grep NotePro".
If the device is already registered on the beta program I'd need the WiFi MAC address to query the beta program.
You can PM that to me if you like.
