Note 10 still has not got the update and i believe note 9 is still in the beta stage so you are probably at another 3 weeks to a month until Android 10 comes to the note 9, but it will be here soon enough! They are being a bit faster this time around, hope you have a great new year!
Official release is complete and was sent to beta testers in the UK and India CONFIRMED.
They gave them first access for helping in the beta program. So it's coming really soon for everyone else.
