I had to take v20220811 update and then V20220919
the ol'lady never takes updates
I swear I'm just gonna swap it out with my xpl3900 since it doesn't update...lol
you don't need to hold them that long
you just need to wait for the remote to show up in top right corner
fyi I never use the buttons I just add accessory and bt-400 shows up in top right corner
