New - RBE970 Series v9.13.1.2 Firmware Via Auto Update

You could check to see if the update pops up in the Orbi app when you check for firmware update, but as FURRYe38​ said, it may not be released to every user yet in the US or in any other region.   There is usually a delay from when small numbers of users start seeing it to when it posts on the NG page (sometimes a couple weeks or more) and depending on how stable it is, could be even longer before everyone sees it or it posted on the download page.
