Hrm I think PC achievements are being listed differently than Xbox One achievements, at least for some games (win32 games maybe?).
Played a bunch of Wolfenstein II via my PC game pass and got achievements. The Xbox One console shows the achievements but they all have a blank background. When I go into the rewards app it refuses to acknowledge that I’ve gotten any Wolfenstein II achievements for the rewards quest purpose.
I don’t even know why it bothers me, it’s 200 points or something lol. It does though because my OCD has me going into the rewards app every few days to see if I should do something to get more points and it’s just taunting me.
