My realms are not working properly

Every time I join a minecraft realm of my friends everything is frozen and I can't go in my inventory but I can break blocks.when i break blocks it doesn't give the block to me.i also can't open chests or shulker boxes.i have tried to leave and come back .every time I leave, all the stuff I did is reversed like it never happened. Even though the game is frozen players are frozen to me but enchantment tables animation is not.please help fix this so I can play on realms with my friends again.thank you.
