AT&T Note9 Pie OTA Rolling out Live

Okay, so I just flashed to ARL1 through Odin and so far it is successful. Now I am going to flash to Pie through the SD card. Hopefully it works.

Update: Updated to Pie successfully. Did they disable the battery percentage for Pie? Can't see it anymore unless I slide down quick panel.
Is your note 9 an unlocked version?
 
For the record, everyone saying you must be on 1ARL1, on Jan 16, my at&t Note 9 went to 1ARL2, then went to 1CSAA on Feb 1. Should it have not worked like that?
 
Where can I find it? And is there a step by step guide somewhere? I haven't used Odin in awhile.

Xda can explain step by step
But watch some you tube videos on flashing on Odin
Google latest Odin download
It's too long to explain the process here for you
