Chat has long delay (up to an hour) before appearing.

Summary:
Chat on Realms has a long delay (which could be up to an hour) before showing up.

Steps To Reproduce:

1. Log in two different accounts/devices to a Realm.
2. Type a message into chat on one device.

Observed Results:
The chat message will not appear immediately on a second device, instead it takes up to an hour.

Expected Results:
The chat message will appear immediately on a second device.

Notes:
This only appears to more accounts on a Realm, not the sender. The message will appear to the sender immediately. As well, only the messages from others will show up later, the sender's message will not appear twice.

Original Description:
Chat does not show up at all and then floods the screen after lagging for different times (can be up to an hour!)
