How to delete a message or chat?

Individual messages and entire conversations can't be deleted on their own. The only way to remove a chat is by removing the match.

How to remove a match:

1. Go to Chats.
2. Select the match to open the conversation.
3. Tap the menu icon (⋮).
4. Choose Remove and confirm.

Note: once a match is removed, it cannot be restored, so be sure before you confirm.
