contrary to my expectation switching logged in microsoft accounts on windows does not change the ingame used player, only changing ingame nickname and possibly appearance based on (bought) clothings. Local play and player connected over the network are affected, Realms are not affected.

Steps to Reproduce:

I use the Xbox console companion app to switch logged on Microsoft accounts

1. Be logged in using Microsoft user A on Minecraft bedrock (java is original Minercaft).
2. Play a local normal game, get items or even leather clothes.
   Potencially let another player, B  join over the network and make that account acquire different items.
3. end game, logout player A or switch microsoft accounts to the other player B.
4. Start minecraft and load same world as previous microsoft user(A).

Observed Results:

You are now basicly the previous gamer A, not your (B) own items nor a fresh empty one.
I can understand the items and other ingame related data to be stored localy, and thus switching accounts doesnt transfer my items nor stats over from another machine, but I expected atleast an empty fresh, spawn at spawnpoint gamer.

Using the same microsoft account on a second machine, allowing the other to get "sign out" allows me to continue to play on the first machine and play as the "same" user and join the first on the first game. thus, 2 of the same players are logged in, sharing ingame names (with an "(2)" added to their name). This new player however starts with an empty inventory and no stats, as if spawned for the first time. (might be another login bug unrelated to this one)

Expected Results:

• Either dissallow starting other microsoft accounts created worlds.
• Allow a user to set an allow option
• Allow any user to start local stored worlds but use different ingame userprofiles/storages
  Or allow a user to choose to use the creators account or create a new one.
• Atleast WARN the new microsoft user that this world was not created by him/her/they.

Screenshots/Videos:

Im logged in as Microsoft account Cathmuts

Now im logged in as user HackBird and I start at the same location and same inventory. This is not what I expected.

Potencially unrelated login bug, a second Cathmuts remotly logged in (that spawned new, empty at spawn) I still holding all items and stats, able to play.

Remote laptop logged in with Cathmuts (the game dint allow this at first, might be related to an other "login" bug, but was able to "logout other instance" or whatever it was called).
I atleast expected this user to get the inventory of the HackBird user, but no, it was a fresh new user. if wanted, needed, a screenshot of how my Hackbird user looks on this "remote" laptop looks is possible

Notes:

I cannot easely reproduce the login message, as I expect that to be related to anoter "bug" I will only try to eport that one if you, Microsoft/Mojang believe that to be an issue. as I see the game adds "(2)" to the name, I dont see much of a problem.
The problem/bug I see is the possibility to login using my own microsoft account and mess arround in someones elses local stored games. we donot use seperate windows user accounts, just our own microsoft accounts. Look at the expected results for my ideas of what I expected or expect this problem to be "fixed". A simple GUUID compare between orginal creator and now logged in user with a popup saying something like
"You did not start this game and these are not your items, are you sure you want to continue? maybe ask for permision or login using the original device you played on".

I thank Mojang for creating and maintaining these games, Java is original. Microsoft, thanks for the original xbox and pumping money and resources into this game. I love Linux more, but thanks to bedrock and my spouse, I keep windows somewhere . Dont dig straight down.
