my xbox time played not tracking

Sometimes these things happen. When they do, they usually fix themselves within a few days. If however it hasn't, then try removing your account from the console, and put it back on again. Here is the link with instructions on how to remove and add it
back.

You would think it would show it in the general stats page. Maybe it does, I hardly look in there lol

It keeps track of your hours on the save file itself, go to save or load and look at the info below.

Same here. All of my games have stopped tracking time. Minecraft has been stuck at 84 hours for over a month and ive played it daily since then. Red Dead Redemption 2 is stuck at 27 minutes.

Same issue here. Signing out does not fix it. Contacted Xbox Support, and they had no solution except to wait a few weeks to see if it "catches up"...

My friends time played updates daily, whereas mine doesn't update at all, or when it does its very random. I have played Destiny for over 60 hours and yet it still shows 9.

Tried rebuilding the profile, resetting, clearing advanced dns, cache, etc. Nothing works.

Xbox support will follow up with me in about a weeks time, and when they do (if they dont I will call), I will have the case escalated since a lot of others are having the issue as well.
