Nintendo switch realms

Have you an active Nintendo Switch Online Subscription? I ask this because I found the following Q/A on Minecraft Nintendo Switch FAQ:

Can I play Realms on this edition?

Yes, Realms is available on the Bedrock edition of Minecraft for Nintendo Switch. To play online on a Nintendo Switch, you need to have a Nintendo Switch Online subscription, so this is a requirement for playing on Realms. More information about Nintendo Switch Online can be found here.

Furthermore, can you post the entire error message (better a screenshot/photo)?

Also, just a reminder that to play online on a Nintendo Switch, you must have a Nintendo Switch Online subscription. So this is a requirement for playing on Realms.

i help nintendo switch minecraft realm aka.ms/accountsettings

Hello thanks for your email . since this is a nintendo / mojang issue . perhaps you can direct the same question on their support forums.

I am unable to create or join any realms on my Nintendo switch and all of the other people asking for help seem to get the same answer or some variation of it "go to xbox live setting and change cross platform play" wich i dont get since they all
clearly state it's for Nintendo switch and i shouldn't have to get a subscription service to fix an issue for a separate console i don't have

Hi! I think I might have found something related to your question in a different forum!

Check it out and see if it works for you,

1. make sure you are on the adult account, if on a child account.
   
2. Once on the adult account, hit the guide button on the controller(Xbox symbol that lights up) this pulls the menu on the left side.
   
3. Scroll right to the gear looking icon, go to settings.
   
4. Once in settings, you will be on the account go to Privacy and online safety.
   
5. Then choose Xbox live privacy.
   
6. You should see the options, child, teen, adult, view details and customize, contact preferences.
   
7. Go to view details and customize, then communication and multiplayer.
   
8. The two you want to make sure say allow and everybody are:
   
   1. "you can play with people outside of Xbox live" set to allow
      
   2. "you can communicate outside of Xbox live with voice and text" set to everybody
      
9. When you launch the game there is also one in the game settings. If not there then they removed.
