I have been trying to set up a Realms server for three days. I have read minecraft.net, which sent me to xbox.com, which sent me to microsoft.com, which sent me to xbox.com. So far, a partial list of the things I cannot do are:

(1) determine which version of realms i have (bedrock? unknown)

(2) determine how to approve invites I sent to others

(3) cannot get any other devices in my home (all of which have minecraft) to be allowed on the realm - "xbox permissions are incorrect" is the error I get. I had to create microsoft and xbox accounts for every device AND reset the persmissions for them individually, but had no luck getting the devices connected. Xbox support personnel were... unhelpful.

(4) I cannot manage the list of invitees - I can't even see it. 

(5) I can't find an account (Microsoft, XBox, Mojang, or here) that lets me see and manage the installation of Minecraft on my computer (or any of my devices)

(6) I can't find how to delete a realm, or delete Realms entirely. 

At this point, I am giving up. All I want now is to delete the entire Realms experience, but I can't even get rid of the software. Can anyone help?
