This is still happening in 1.19. Very annoying paying for realms when you cannot uphold a service you charge people for !! MCPE-12347
I am now experiencing this problem also, i've contained two ghasts while I build a farm in the nether and i can't even fire arrows at skeletons and lava pots take ages to register. as Paul C has said, that pretty much summs it up except I am experiencing this on 1.19, once I leave the active chunk there are no problems.

I am in australia, sydney. My realm was purchased by me, it is a local realm.
I do not have any internet troubles, i dont lag in any other game, i dont lag in other peoples multiplayer worlds, i do not lag on java servers.
You can clearly see the latency problem caused by YOUR REALMS SERVICE. I have asked your garbage technical support for a refund because of this and they keep giving me automated responses trying to tell me its my ISP and or DNS servers. IT ISNT.
