After the newest update the realm I have has become broken

It takes multiple times of reloading the whole game to load the realm due to it telling me it disconnected from servers or couldn't load the world. When I finally get into the realm it takes me a couple hours back from where I originally saved and everything is lagging slightly. There's no animation for braking blocks and the sound lags behind the block will disappear and take a good couple of minutes to appear as an item and no matter what I do in the world as soon as I log out it reverts back to he same previous save
