Profile Switching

I am playing Halo 5 (X-box game pass) on my profile on with my roommates Xbox and I can’t find an option to switch to my profile. I played this last week just fine, I had to sign on my profile before the game loaded but it worked. I tried this today and it did not work. I was working on leveling up and my stats weren’t loading. I played just fine on my roommates profile but i want my stats and my profile because I pay for it. Where is the option or how do I fix this?

Is the game pass subscription under your gamer tag or your friend’s?

It fixed its self. Maybe. Mine.

I am having this problem again. His proflie got logged in and now mine is having trouble again.
