Signs, Chat and Name Tags Broken in Realms

I am experiencing the following issues on Minecraft Realms:

• Chat does not seem to work (Other players cannot see sent messages),

• After placing and finishing editing the text on a sign, the text on the sign will disappear. 

• When naming a name tag, the newly named tag will disappear shortly after it is created

This is just on the one Realm, I can't test on any others as I don't have any others. I have tested downloaded the Realm world to my computer and playing multiplier from it locally and these issues do not occur. I have also tried reuploading the world. Have also tried closing and reopening Minecraft.
