So a friend group started using WhatsApp. I’m new and can’t figure out if people have read my message. When I get info on the message I see the following link n the screenshot.

Two grey checks so I know it’s been delivered but the two blue checks with three dots next to it instead of a time is throwing me off. Does this mean it’s been delivered but not read? Or that it has been read? And what do the three dots mean?
