Have the same worlds on the same account but different devices

So, dear Minecraft, I don’t know if you heard it often or not but imagine you have like a super duper world you wanna keep forever and that world is on your iPad but the iPad stops working one day, you need a new one, but that means the world is gone too and that’s the issue. Being able to log in into the same account on IPad and phone but not having the same worlds on the phone, and that would make everything better if you changed that. Those worlds really mean a lot and we don’t wanna lose them because it’s only on one device even though I am logged in the same account. So please change it. Take it to heart, no matter if you heard it often it’s probably a common issue so yeah. I really love playing Minecraft but it just would be really sad if those worlds were gone.
