Xbox Live Ultimate Game Pass rewards

Ok my question is, how do we get the perks, from the windows 10 xbox app?

I keep getting a message:

Sorry, we're having trouble showing the details of this perk right now. Try again later.

This message pops up for all perks not just the 2 for pso2?

Is there something i am missing? or does it apply to only those who have a recurring subscription (meaning renewed after the 1st 3 months)

I'm getting this also. It never used to happen. Just randomly did right before episode 6 launched.

People say use the mobile app since it works. Huge pain in the arse but I may have to try it.

Got them tonight from the xbox app, guess waiting for things to work pays off in the end
