How do I know that my messages has been delivered or read?

Messages receive a single grey coloured tick once they've been delivered. Once the message has been read, this tick will show as purple (in light mode) or turquoise (in dark mode).

As part of our design technique to keep your chat space clean, we do not display the deliver and read receipts on every single message in your chat. Instead, these receipts are shown only on the most recent message sent.
