What I expected to happen was...:
I hope to enter realms after the update. 

What actually happened was...:
I am unable to connect to realms.(Not even the list would show up) I was playing fine before the update. I tried deleting the game and downloading it again but it did not work. I can play single player fine. Minecraft says an error occurred (500) but my internet connection is fine.
