Disconnect from realm when leaving or entering the nether

So this has happened a few times now but every so often.

While in the nether and a player try to leave the nether to the over world all players get kicked from the realm.

We are able to rejoin back on instantly but getting removed alot of the time from just going through the portal is annoying.

Everyone is playing on different devices Switch 1, switch 2 and pc so it’s go to do with realms itself
