shared microsoft account games crasing

What do you mean by "sharing account"? Do you mean that you both are logged in to the same account on two consoles? If so, you can be logged in to your account only on one console at a time (you can find more details in this
article).

good evening

it's not the same and they can't play at the same time

On pc As tezz says it's simple but dangerous and not recommended to be attempted outside your own home and the more pcs you attempt.it on makes it more difficult

Because to download the said game you need to sign in

But then tou switch profiles.to have own achievement

Giving out your password is NEVer a goof idea and a violation of the terms of use

there is but i won't say if you are sharing outside of your household, sharing is simple on pc including gamepass pc but it is better to be in the same household even if it is multiple pc's.

The Wavebreaker add-on is for in-game cosmetic items. It is linked to the Epic Games account it was purchased on, not necessarily your Microsoft account. Family sharing will not share the item with him.

If the item was not purchased on an Epic Games account linked to his Microsoft account, there is no way for him to use it on his Microsoft account.
