Same Microsoft account joining.

As a little Minecraft family, my children and myself would play multiplayer with us all logged into my microsoft account. I have bought worlds from the market place specifically for my son and daughter so I would appreciate it if we could all play together on my microsoft account so I dont have to pay for these worlds again on new accounts for them. They are useless on my account otherwise. I was devastated to not see them pop up for me to join after the nightmare I had getting our games updated and logged in. Please fix this so we can play together again.
