Stats not tracking achievements only today

As long as the game shows it complete then it will pop at some point, ot can be a while though

Check in the game if you have earned the achievement.

Says you have gotten it but no extra gamerscore? - Just wait, It will come soon. I once got an achievement from a game that I stopped playing months ago.

they can take a day or two to catch up, also go to trueachievements.com for specific issues, they have some troubleshooting check to see if your achievements show up there.

I'm unsure concerning there being a new UI update where it would have gone to... but TrueAchievements does have stat tracking for hours logged on most if not all games you play. Its free to create an account, its the most official unofficial website for
tracking stats and achievements that Xbox has to offer.

You should be able to see the stats for the game played.

Go to All Achievements and click on the game you want to view. There will be a tab to the left that says "stats" and it will show you the time played.

You can also see it on the mobile app by going to Achievements, and click on the game and it will show the information for the game including gamer score, achievements unlocked, and time played.

No, friend. The most of stats for abox games are empty.

There aren´t any stats on xbox neither in archivements nor in app nor in profile page on pc

I wouldn't be surprised if it's only temporary. Some other features have been temporarily removed due to the amount of people suddenly online and I wouldn't be surprised if tracking stats was one of them.

I'm sure they will come back.
