New Xbox App does not have achievements/store...

as the xbox app is actually a frontend for the windows store, windows store does all the backend stuff including downloads, can you search xbox games on windows store and install from there until a new update comes out for the xbox app.

Found out this is happening with more of my games, so there is something wrong with the communication between all apps and logging in/app store. I still have a log in screen and can actually make purchases from my PC. I just can't sync the achievements,
and they don't even think I'm logged in. This happened with the new game "Touchdown Hero: New Season", but another new game "Alto's Adventure" syncs achievement data correctly.

Should I remove the device from my account and re-add it? Or is there an update for the app store that corrects this problem?

Hello VP33,my name is Oskayra, I will be happy to help you in any way possible.

Yes, there is a sandbox to test achievements for UWP apps on Xbox. It's called Xbox Achievements Sandbox.

The Xbox Achievements Sandbox is a tool that allows developers to test their app's achievements in an isolated environment. This is useful for testing achievements without having to publish the app to the Microsoft Store.

I hope the information is helpful to you, if not, let me know that I will be happy to continue helping you, good luck and happy day.

Sincerely,
Oskaira.

If you have the xbox app open it up and go to the game and look at achievements for it. Does that triggure the achievements showing? Ive had this happen to me and this was how I fixed it.

Hi, if the PC games that you're playing are from the Microsoft store you can also check the achievements using the Xbox mobile app:

And I want to confirm something, these missing achievements are for games that you're playing using the Xbox app / Microsoft store, right?

I ask this because most of the steam games or other stores games aren't compatible with Xbox achievements
