Showing 'kept' receipts to other party on audio messages when I haven't kept them
I have read receipts off (for all contacts) when it comes to my text messages. So I assumed that would cross over into audio messages/voice notes i.e. even if I were to listen to one that someone sends me, they wouldn't get a 'read' receipt.
However, I was experimenting by texting my sister, and whenever I click play on an audio message, it automatically says "Kept [insert time here]" on her side of things ... when I haven't kept it. In fact, it doesn't even give me the 'Keep' option.
Does anyone know why that is? And how I can turn it off so no 'read' or 'kept' receipts are sent at all?
