Thanks. Looks like Gaming Services is now a component of the Xbox app (perhaps it has always been),
Interesting that your Game Bar version is more recent. I checked this morning & all my store apps were up-to-date. Just checked after reading your post & see 2 new updates: Movies & TV & Xbox Game Bar Plugin! Updated, but the Game Bar version is still the same - maybe a reboot is needed…I’ll confirm later.
[ Edit: 24-hrs & 1 rebooted PC later, I’m still seeing the game bar version reported as 7.124.5142.0.]
[ Edit 09/17/24: the current versions on my PC are now:
2409.1001.5.0 (Xbox)
23.92.22001.0 (Gaming Services)
7.224.9031.0 (Game Bar)
I try to keep the current version listed in this post.
