Rewards not showing up after using gems

The credits should show as pending on the Rewards site. They would be scheduled to be deposited into your account at the end of the month.

Hello,

From the FAQ on Vault Credits:

I claimed Rewards Credits from the vault. When will I receive them?

If you claim Rewards Credits from the MyVIP Vault, they should appear as pending in your account within 96 hours. Once they are pending in your account, the normal deposit process kicks in. Generally if you have over 5,000 Rewards Credits pending in your
account in the first half of any given month, that amount will be converted to your local currency and deposited into your Microsoft account on or around the 30th of that same month. If the Credits show as pending in the second half of the month, that amount
will be deposited into your Microsoft account on or around the 15th of the next month.

Please note you need at least 5,000 Rewards Credits pending to automatically trigger a deposit, though you can request a deposit for the next scheduled date as long as you have 1,000 Credits pending. Also, if you have ongoing issues with us depositing
into your account, such as your account not matching up with your billing location, you might want to consider choosing a different prize from the vault, as we won’t be able to deliver your Rewards Credits until the deposit issue is resolved.

Multiple achievements in Forza 7 that noted Gem earned on screen that have shown up.

The gems that show up when you earn an achievement is just to note that it is a rare achievement. It doesn't have anything to do with gems earned through the Rewards program. In order to earn gems you either have to complete a challenge (which are listed
on the Missions page of the rewards site), complete offers, and you can can earn gems for every 1,000 gamerscore you earn and/or reaching new achievement tiers.

I think I may also be having this same type of an problem since I just yesterday tried to use some of my gems too for an 250 Gem reward, no email for that one yet.

5,000 Rewards Credits for 250 Gems ,

but in any case I have yet to get an redeem email code for it, not really sure where I need to go for them to send me my code anyway, it sounds related to some of these problems report on this forum. I think it should convert the points to Microsoft rewards
points correct, so I can use it on my xbox one, anyway if it was an direct $5 dollar deposit that would be fine, but I don't think its show up on my account yet. it sounds like their having problems with some of these 250 gem rewards , I used an 100 gem rewards
also yesterday I got an email for that one, but not my 250 gem reward yet.

If you're talking about using gems to redeem rewards credits, they should show as pending after 96 hours. Then they would be deposited by the following 15th or 30th of the month. If they're not showing as pending, you would need to post in the Xbox Rewards
Questions support forum.

If you're referring to Microsoft Rewards points, you would need to contact customer support for the Microsoft Rewards program via their redemption page.
