Achievements don’t save cross platform [resolved]

In Minecraft, when you get an achievement the achievement is not saved to your account but instead to your device. Because of this I can't access all the things I unlocked for character creator. If it has been collected it can be used anywhere but that means I have to go through all my achievements on each device. To fix this you can make rewards automatically collect and/or achievements upload to the server instead of saving on devices. (The same problem and solution with worlds, the are saved onto devices.)
