@emilime have you gotten a reply back from xbox or playstore about the purchase yet? sorry Mojang support hasn't been super useful :/

nothing from @XboxSupport :( (I did not contact Google Playstore because the purchase of Minecraft coins went well, no bug on their side)

There was a bug in 1.4.1 that caused this that should be fixed in 1.4.2. Does it work now?

yes the bug appeared in 1.4.1 version but I updated to 1.4.2 some days ago and nothing has changed, my download is still blocked :(

"So talking with the team we only had one device that had the same behavior you're talking about during our testing. And the only way they could fix was with a reinstall. Have you tried that yet?" If you do, please back up your saves!

another update to Minecraft (1.4.4) and download of this word is still blocked!!! @MojangSupport please give me the money back!
