Youtube and restricted mode with NEXTDNS

Hi there, 

I search a lot, but did not find a thing to help me.
But now, looks I have a solution for the YouTube restricted mode activated when using NextDNS.

i made a lot of trials to really identify NextDNS as a "issue".
On any device on my network (protected with NextDNS of course) all YouTube accounts are in restricted mode. 
On my phone, for example, on cellular restricted mode is disable, on wifi, "my administrator enabled it" :
 

Restricted Mode

Turned on by your network administrator to help hide potentially mature videos.

Long story short, YouTube provide a URL to test and understand what's going on : https://www.youtube.com/check_content_restrictions

And I saw some restrictions :
 

DNS restrictions are on

Moderate restricted for www.youtube.com, youtubei.googleapis.com, www.youtube-nocookie.com, youtube.googleapis.com, m.youtube.com

Adding these URLs to white list my do the trick (I'm gonna test :) )
