I don't know if you're on Android or an Apple device. This is not a required update, so to go back to the non-beta on Android, the short version is this:
-On ASIair reset the firmware to the "default"--or the version it shipped with.
-Uninstall the ASIAir app on your device.
-Install the app (ASIair) from the app store and NOT the download in this thread.
-Update the firmware on the ASIair when prompted.
You should now be on the production and not the beta version. At least this is what I've had to do.
