Trying to join my game takes the other player to a different game's store page.
I bought SE for my granddaughter last week and when she was last here she was able to join my game from the Xbox guide menu. Just now she tried to do the same and it kept taking her to the Ghost Recon Breakpoint store page. I did a full restart and it still did the same thing. I finally got her into the game by sending an invite but her trying to join without it is broken. I could understand it taking me to the SE page thinking she doesn't own it (despite being at the menu) but not a totally different game. Both consoles are connected to the same network and I have an open NAT.
