The client (minecraft) freezes when I play in my realms. This happ2ens when I move around the world. Other players of my realms also have this problem!
Fortunately for me, this is a trial version of realms, otherwise I would be very disappointed.

After some time (a very long time), the client (minecraft) returns to normal, but if you move around the world again, the error appears again. (It happens that the second time freezes forever)
These hangs are also affected by mobs.
When you turn off the world parameter: the appearance of mobs-these freezes become less prolonged, but still remain and this very annoys me and my friends.
