i bought java edition minecraft and i cant redeem a code for windows 10 edition

I am trying to redeem a Minecraft windows 10 edition key from the Mojang website.

This is the prompt I am trying to redeem from:

--------------------------------------------------------------------------------------------------------------------------------------------------------------

Minecraft for Windows 10

You bought Minecraft: Java Edition during a period of time when Minecraft for Windows 10 was included for free. Claim your redeemable gift code by clicking the button below and follow the instructions. As you
might have guessed, Minecraft for Windows 10 can only be played on Windows 10.

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

It allows for users who have purchased the java edition of the game to then redeem a code for the windows 10 edition of the game.

This is the error message that pops up:

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Error! It looks like we've temporarily run out of gift codes for Minecraft for Windows 10. Don't worry though, more codes should be on their way. Please check back later!

Thanks for any help!

I bought the Windows 10 version of Minecraft by mistake, but the one I wanted was the java edition.

I saw that anyone who buys minecraft java edition is entitled to minecraft Windows 10. Is the reverse also true? Who buys minecraft windows 10 is entitled to minecraft java edition?

If so, how do I access the java edition version at no additional cost?

Also again my order history will NOT say I purchased Minecraft because I did not. As stated before, I got minecraft bedrock because Mojang gave a free code to redeem Bedrock for all Mojang users that purchased Java Edition before a certain date see article below:

How do I get free bedrock if I have Java? (wikilivre.org)

"Windows 10 has the legacy Java Edition as well as the modern Bedrock Edition. If you bought the Java Edition before October 19, 2018, you can redeem a free copy of the Bedrock Edition. You can also buy the Windows 10 edition directly from Microsoft for $20."

I did redeem this code, so again what gives?

The Minecraft Editions, like the Starter or Master editions. Is what i meant by packs. And when i bought the java edition of minecraft it let me redeem the window ten version.

I bought the Java Edition and migrated it to the Windows 10 Edition, does this not give me a free version of Windows 10 Edition Minecraft, I have to re-buy it?
