Pop up notification every 2 hours or so on my QN90B

[EsQueue]

For the past 2 days, I've been getting an EXTREMELY annoying popup notification with small ding sound. This pops up about every 2 hours and disappears in 5 seconds. Impossible and just plain silly to not be able to read it. It does say something about thanks for being a customer and that smart hub collects data in some kind of way and that you can mess with settings in settings. I have never been able to read it as it leaves so fast. I just disconnected it from my network prior to posting this. Anyone knows what this is and most importantly, how to stop it? 

I only hope that disconnecting it from my network will stop these messages but only thing I can find under privacy settings want me to agree to a bunch of check marks. I clicked none of them as I do not agree with their TOS for something that I rarely use. This TV is strictly as a monitor and have no antenna connected. I could completely disable smart hub as I may just have by disconnecting the network connection. 

UPDATE EDIT: 
Taking the TV offline seemed to have fixed the issue but the loss of IP remote control via watch and home assistance is an annoying too. My plan is to Block the TV's mac address from any WAN (Wide Area Network) access via my router. I'll put it back on the network so that my home assistance setup still has access to it so I'll still have my remote control features but the TV and Samsung has no access to and can't make changes to my purchased and owned property.
The TV is used as a monitor like I said so a dumb tv will be fine if I can't get it to work how I mentioned. I'll update if anyone even cares about that route.

UPDATE 2: I have since reconnected my TV back to the network and instantly saw the warning again. I then blocked WAN access of the TV via my router but it is connected to my LAN only. 
I then disconnected my phone offline to test and still have access to my Home Assistant features to the TV online as that is via a encrypted DDNS running through my own micro PC setup along with every other former cloud device I own. All controlled by me. Now Samsung can't break what they can't connect to.

I've unchecked every box, and signed out of everything..  if it keeps happening, I'll get a dumb tv, and never buy anything samsung again.

I'm also getting this on my Samsung 77" S84d series 4K OLED Smart Tizen TV  the past few days. Any luck with the fix yet?

I too had this issue, but this is how I resolved it. 

Go to All Settings -> General & Privacy -> Terms & Privacy 

Scroll down to Viewing Information Services and select it. For some reason "I agree" was checked. Uncheck this and "Confirm".

I noticed the item below it, "Interest-Based Advertisements Service U.S. Privacy Notice" was also checked so I unchecked it as well.

I believe what happened is the last Samsung update must have slipped these in "under the covers" (or I'm just entirely blind and blew through them).

Hopefully this helps. It was extremely annoying.

I'm also getting this notification throughout the day. It even plays a little bell sound when it pops up. I cannot find any setting to disable notifications.

QN95B here, I get the popup but without any OK or close button. It just appears and disappears before I can finish reading it. Happens on all inputs, even HDMI
