Windows 10: Purchased Minecraft but will only let me play in demo mode

Absolute amateurism on the part of Microsoft and Mojang. I bought Bendrock. I bought Java as a standalone license. I bought both licenses for my kids and I bought the mobile versions. It worked for a few months, but today...When you try to ligin "can't log in" you can buy the full version :

Purchased Minecraft Collection but will only let me play in demo mode

3 days ago I purchased "Minecraft for Windows Starter Collection +Launcher for windows 10 and 11". The Launcher has been frozen since 2 minutes after purchase...useless...but somehow, Minecraft did install. It is installed and lets us play the demo mode only. Unless I pay for it...again. I can't get a reimbursement and we can't play the game? We don't own an Xbox. Also, our brand new purchase of Minecraft wants us to buy it again and we'll get a bonus Java edition. Ugh. Please help! Been running in circles for 3 days now.

Paid for Minecraft, but it is still in DEMO mode

Paid for Minecraft, but it is still in DEMO mode - about a month ago. Money moved from my bank account, confirmation email received, and inside the Windows account everything looks legal and official, confirmed. BUT she cannot play it anymore - DEMO mode
has finished. Shall I reinstall it? Or install it under my account?

 

Minecraft Windows 10 stuck in demo

I cannot get Minecraft for Windows 10 to work properly. I downloaded the demo, then redeemed my full version through the Mojang store (because I have Java Minecraft for Windows too.)

Now I have 2 copies of Minecraft in my purchase history and it only ever allows me to run in demo mode. If I click the 'purchase' button in the demo, it says that I already own it.

When I try to access Microsoft's help, it only offers US phone numbers. I cannot find Australian support. Any idea how I can get the full Minecraft for Win10 to work or how I can get in touch with a relevant, local Microsoft person?
