Just wondering because a few days ago one of my contacts had their profile picture suddenly disappear and become replaced with the standard white outline of a person on a blue background. The last message i sent to them failed and i was just wondering if this meant they have blocked or removed me?
what icon do you see opposite their name? do you see them as online, away, or do not disturb?
if the icon opposite their name became grey with the question mark inside, and the phrase that that user has not shared contact details with you is being displayed, then they have removed you from their contact list.
