Same problem here, this is what the nordvpn support said:
AGENT (Freddie): Please visit dnsleaktest.com/ while being connected to NordVPN and perform both of these steps:
Take a screenshot of the IP address that is shown on the main screen of the website;
Click “Extended test”, wait for the test to fully finish and take a screenshot of the IP addresses shown in the result.This information will help me identify whether there are any issues with your connection.Please make sure to upload both of the screenshots in .jpg or .png format.A guide for taking a screenshot on various systems can be found here:https://support.nordvpn.com/1478741782You can click the “Options”/Paper clip icon below this chat and then click “Send a file”.
USER: I did it few hours ago, doing it now
AGENT (Freddie): Okay.
USER: give me a moment
AGENT (Freddie): Take your time.
USER: Thanks for waiting
USER: downloadable message
USER: downloadable message
USER: it shows cloudflare because in the nordvpn app I selected 1.1.1.1 DNS, with nordvpn automatic dns doesn’t work neither
AGENT (Freddie): Try using the NordVPN DNS addresses there and redo the test:103.86.96.100 and 103.86.99.100
USER: I have to set them in the nordvpn app, right?
AGENT (Freddie): Yes.

AGENT (Freddie): Got it.
AGENT (Freddie): The problem of such DNS addresses being visible while using the VPN connection on TV devices has been reported to our developer team.With these DNS results being visible it can be expected that you will not be able to access some websites or streaming services, as the locations of the public IP and the DNS address are different.Nevertheless, the developers are aware of the issue and are currently working on a solution.However, we would rather not give you an estimation when we do not actually have one for certain.Telling you that it will take 5 days and if in reality, it ends up taking 2 months - would be bad for both sides involved.We understand that waiting is rather frustrating, and we can only apologize in the name of the company.
USER: But with the cloudflare dns it shows uk and it gives the same exact problem 
AGENT (Freddie): Streaming with different DNS addresses may not work.
With nordvpn dns dnsleak shows Frankfurt, but with cloudflare dns (1.1.1.1) it shows UK. After the chat I tried the google’s DNS (8.8.8.8), it shows UK but still no Disney+/BBC so I’m pretty sure that there is another problem
