What can I do on the PvP/Event Chat tab?

To access PvP/Event Chat, you need to tap the Arrow button on the right side of the PvP/Event screens and then tap the "PvP/EVENT CHAT" button at the top.

Note that this button will only appear if you tap the Arrow button when on the PvP/Event screen.

On the PvP/Event Chat screen, you can see messages that other players have posted, and you can tap the "Enter Text" box at the bottom of the screen to write a message.
