Realms 1.16.210. Character defaulted as second player on split screen.

Realms 1.16.210 xbox...second character to log in...Character defaults on split screen. Will be requesting refund if this is associated to known bug that has been going on for over a year now. We signed up and are paying for realms and playing via realms due to the original bug MCPE-55815. I can play as primary to get original character, but as soon as I go back as secondary/split screen it reverts to a default character.
