I downloaded the Firebase Demo and input all of the proper site properties for my Firebase project. I'm having a few issues testing in the "Chat Room with Email and Password" screen:

1. When I enter the screen for the first time, it seems to work fine. When I refresh the screen, however, I get one of a few errors and my messages don't show up immediately anymore (I have to refresh to get it to show up). This may just be an error with the Demo module specifically, but it's interrupting my testing. I have to delete the user from the UserFirebase table to restart the test.

2. I logged in two new users from two different browsers and entered the screen at the same time. I sent a message with both, and the first message only showed up in real time on the screen of the user who sent it. The second user was only able to see the first message after sending his own message. This means the real-time messaging is not working. How can I fix this to test successfully?

I followed the instructions and input the correct values for the properties, so I don't see why it shouldn't be working. I also do not see any data in the realtime database section of Firebase, although I'm not sure if I'm supposed to. I'm still new to Firebase, so any help would be much appreciated!
