Inputs/not being able to interact with any blocks

Hi

Im having issues when playing on realms (PS4) I seem to not be able to open my inventory or open the crafting menu and I can't interact with crafting blocks. Also on my end I can freely move around but from my friends pov I'm not moving and the world doesn't fully load in. This only happens on realms normal worlds are fine and servers like the hive also work with no issues. 

Please can help resolve this issue.

Thanks

James
