What's the easiest way to link up with Xbox one friends?
First: did you and your friend join the same pact? If not, then you're technically enemies in the game. If you've not invested too much time, you can restart. Just be sure both of you select the same pact.
If you know your friend is online, you can ask where he's at and try to meet up at the same place. I don't know if "megaserver" is just one massive server or if ZoS load balances, meaning you could be playing on one server while your friend is in another.
I'd also recommend creating a guild. Not only can you invite your friend, but you can invite others as well.
I know there's a way to teleport to your friend, but I'm not sure how it works on console (or if it's a PvP option only). Someone may offer assistance with this.
It's kind of a pain in the ass. The easiest way is to join the same guild or create one. That'll give you guild chat to communicate from anywhere and also the guild roster so you can select them to invite to group. Is unbelievably stupid that you can't select from a list of friends when creating a group. Once you do group up with your friends the group stays together even after logging out provided you don't leave it.
