T-Mobile ARJ5 update has arrived

Is everyone getting this annoying pop-up every time you enter a different message conversation? I've never seen noticed this before on any other updates.

Looks like RCS messaging.
I got the RCS update on my S8 a few weeks ago. That phone is not giving me these pop-ups. Once you select cancel for each thread, it doesn't show again. But, it's still annoying.
 
So I checked and I had an October 1st security update for T-Mobile. I think it said a ARJ8...
 
So I just did this update a little bit ago. For those who have done it and had it for a while are you seeing any improvements with anything? Thanks. I just came back from a 2 week vacation and was so very disappointed with the camera. It is very lacking and I miss my Note 5!
 
The unlocked TMo Note9 (N960U1) received the ARJ9 update this morning. It's security-only, with the Nov 1 patch level.

Looks like the unlocked model got the phone-improvement update a week or two before the branded model did, but got the security update a week or two after the branded model.

There were 2 updates this month. The October one, including the camera update, which was late around 11/14 and the Nov security update a few days ago for ARK1, which is close to the time of the month they normally send them out.
