Xbox 360 achievements not showing up

Still can't see my all achievements on Xbox one or the Xbox app for Android or Xbox.com. The only achievements I can see are recently played games, but none of my old 360 or One games show up on the list. . I can view my achievements fine on the true achievements
app for Xbox one. I have to boot up an old game for the achievements of that game to show back up. I can view my Xbox 360 achievements on the 360 emulator also.

It's easy to do, bring up the Xbox guide by pressing the Xbox button, then select the achievements tab, and then select the option to show the list of achievements, and select the option to turn off the achievement tracker.

Xbox 360 achievements do not have achievement tracking. It's possible the Xbox is showing the last game you completed before you played the Xbox 360 game.

My windows phone achievements are not syncing. The achievements pop in the game with the normal achievement notification, and the in game achievement menu shows that I have unlocked the achievement, but the achievements are not syncing with xbox (yes we
know that windows phone games do not show up on the xbox app and only show up on the 360 achievement menu). Please help us. There are many people on Trueachievements with this problem.
