When a player signs in as a second player on XBOX One the player's profile is not loaded correctly

Player A and Player B have been playing in a realm on the XBOX for some time in two player split screen mode with no issues.

However after 1.16.210 there is an issue with whoever is the second player.

Player A starts Minecraft and joins a realm or hosted game.

Player B then joins as a second player.

When a player B game as a second player that player's profile is not correctly loaded.

• The second player does not have their skin
• The second player does not have their inventory
• The second player's endercheast is empty
• The second player does not have their XP

If player A then drops out, and the game restarted with Player B as the main then Player B has access to their correct inventory, endercheast etc.  If Player A then joins as a player two then player A does not have their inventory / endercheast etc.

This only appears to have happened after the update 1.16.210
