All splitscreen players after the first load in with a new avatar in 1.16.210. This is replicated both on realms and local splitscreen. All players in test scenario were Xbox live accounts (ie not guest account). All profiles have access to historical inventory when logging in as first player separately. In all test cases, subsequent logins had empty inventories, no equipped items and empty ender chests. Game is treating subsequent logins in split screen as guest accounts?

This is not the same bug. This only impacts split screen sessions. Not single player sessions or relatwd to timeouts at all. Please do not conflate the issues because they share a theme.

MCPE-55815 specifically says that this occurs in multiplayer, not singleplayer. This bug should be fixed in the next update (1.16.220) anyway.
This issue has already been reported. Duplicate MCPE-55815.
