Cannot purchase on Microsoft Store, Cannot add money to Family Account - how to resolve?

To update this post, in case anyone else has this issue.

The Microsoft Store on Windows PCs intergration Minecraft is broken. Seems crazy given Minecraft has almost 100, Million Users. I suspect Microsoft know the store is broken but are not interested in fixing it, why would they given that the cash goes to them.

You cannot add money to the Microsoft Store for your children in your family account and purchase Minecraft coins/content. (well, you can add the money, but not spend it on Minecraft).

FIX...

I did manage to get this resolved, but you need an XBOX. I logged into my sons XBOX and set up an account for my daughter using her Microsoft account details. I launched Minecraft with my daughters account. Once in Minecraft on the XBOX, the intergration with the Microsoft Store worked. When I went to purchase the content on the xbox, it took the money out of my duaghters account and bought the content. I could then log into her Windows PC, with the same account and the content is there....

The newly separated accounts still say they are unable to change billing settings and only primary member of the gold family pack can do so.

But that is also not possible. Cannot allow them to add credit cards and also cannot transfer money to those accounts. How do those accounts spend money?

I want to clarify that Minecoins are purchased in-game through the Minecraft Marketplace and are not purchasable through the Microsoft Store. You can only redeem codes for Minecoins in the Microsoft Store.

I suggest following the steps on the following page for an alternative to add money to your child's account:

No, the Minecraft Store redirects the user to the Microsoft Store.

The parent gets the email request for permission from the Microsoft Store not the Minecraft Store.

Following the above steps I get this also error PUR-PrerequisiteProfileMissing regardless of whether I try and add money via a desktop browser or mobile phone browser.

This is for Minecraft on the PC & there is no avoiding the Microsoft Store which cannot cope with online payments.

Hello Noah,

Unfortunately, the money on an account cannot be transferred, at least currently, between accounts.

Here we have information for Adding Funds to a Child Account for full details on how an account
may garner money for usage on the Microsoft store.

We hope this information helps and wish you the best!

You can add Xbox gift cards to your account which will add money on your account to purchase content (it cannot be used for subscriptions).
