I have achievements shown in XBOX that are not reflected in the Microsoft Treasure Hunt...

Thanks! I will give that a try.

I'll suggest you report the issue via the hub. See how to do that here https://support.xbox.com/en-US/help/account-pro...

I do not have a separate XBOX console. All my activity is on my desktop PC via desktop applications. In particular the number of Hearts, Dynamite and Pickaxes available in Microsoft Treasure Hunt were at one time greater than they are today. I believe this happened after an OS upgrade sometime along the way.

Kindly try the following;

- Double check your achievement progress on your console. If you completed the requirements to unlock the achievement on your console but it doesn't show, it may not be synchronised with Xbox Live. Allow up to 72 hours for this synchronisation to take place.

- Check your achievement progress online. If the achievement appears under "Achievements" it is unlocked. If the achievement appears under “Locked Achievements,” either the console isn't yet synchronised with Xbox Live or the achievement was not successfully unlocked.

- Ensure you're connected to the internet / Xbox Live. If a completed achievement hasn't appeared online after 72 hours, your console may not be connected to Xbox Live. If you completed an achievement or challenge while offline, you won't receive related notices or rewards until you connect to Xbox Live.

- Restart your console. Restarting your console will ensure that any achievements awaiting synchronisation on the console are re-sent to Xbox Live.

- Remove and redownload your account. The account information stored on your console may be out of date. To update your account information, delete and then redownload your account.

It looks like they made the W10 version of the game even if there's no official info to be found yet. New version has 1000GS insted of 200 of the W8 previous one, so they completely changed the achievements even if the new ones may
be not officially active yet. Discussing the same on TA forum but without much clues since there's no info.

Trying on a W8 machine could be an option, but that is a test to be done more than an actual solution.

Hopefully this will be clarified when some official info are released...
