Yeah this isn't working for me either, maybe someone can help.
I log in as usual, ready to play some PvZ.
I go to the monitor thing in my backyard to activate split screen.
I log in the other player as the guest to my account which has Xbox live.
I go to play a multiplayer game with my friend while we are in split screen and the option is grayed out.
So we tried going into the multiplayer portal in the middle of the garden and, this is where it gets tricky to describe in text. So let's say the top screen 1 is the main account and bottom screen 2 is the guest.
When 1 enters the portal first, it tells me that it "could not verify that you have the credentials to play online" or something similar to that. Even though I do have Xbox live gold.
When 2 enters the portal first, they are able to enter and float around in space while waiting for the party leader to join. When 1 walks in while 2 is waiting for the game, 1 gets the same message as above, and both 1 and 2 get kicked out of the portal.
The only thing I can think of is, do both players have to have Xbox live gold?? I don't want to buy a month of gold just to try this out and have it fail. I can play rocket league with a guest online just fine.
Am I doing this wrong? Is there a separate way to this besides the one I described?
Online multiplayer split screen (we are wanting to play Turf Takeover in a public online game) IS currently active right??
Sorry for the wall of text, just trying to get a good answer since we were really excited for this update!
Thank you very much in advance.
