Research how other apps handle read receipts
Research how other messaging apps handle read receipts:
- Is a message displayed differently when sent to a contact who has disabled read receipts, versus a contact who has enabled read receipts but has not read the message?
- Does the user have to allow read receipts to be sent in order to request that contacts send read receipts?
- Is the user informed if a contact allows read receipts to be sent to the user?
- Is the user informed if a contact asks for read receipts to be sent to the contact?
- In a group chat, is it possible to see which users, or how many users, have read a message? What is the UI for this?
