rewards quests

so this get 50 points for any achievement.. great, love it on my xbox.

But what happens when I'm away from home and I play a game on game pass using Android? After I get my achievement how the heck do I claim my 50 points without access to an xbox? I work 24 hour shifts so by the time I try to collect on the xbox it's too late.

Am i missing something or is there a massive flaw with rewards and cloud gaming?
