When logged into the Realm and another player attempts to join, I am immediately logged out with a connection lost error.  I only get this error when another player is joining, otherwise I can play for an indefinite amount of time and never get logged out.  This only started happening after the update.  I am on version 1.20.8005.0

I checked the other player's version, they are on a tablet with version 1.20.81.01  They are not able to join the Realm at all.
