Issues

When receiving a ephemeral message notification, sender name would show either null or You (but you were not the sender, thus receiving a notification)

Solutions

Verify if message type is ephemeral, if so then hide setting sender name into the notification

How to Test

• Open App
• Receive an ephemeral notification from another user
• Check that neither null or You is shown on the left side of the message, along with Someone sent a Message
