How to enable/disable Read Receipts for messaging

Send Read Receipts is a setting that enables a visual notification to indicate that a sent message has been read by the message receipient. This is represented by a second overlapping check mark  that will appear in the bottom right corner of the message. 

Note: Both devices must have Read Receipts enabled in order to view the message as read. 
If one device has the Read Receipts disabled, neither person will be able to view a message as read.
Additionally, this feature is for SudoIn messaging only.

To enable or disable this feature follow the steps below:

• Tap the Menu icon on the top left corner
• Tap Settings
• Tap Messages
• Tap Send Read Receipts to enable or disable
