Not sure if this is the place to ask this type of question but...

I opened up Valorant today (April 5th, 2021) and went afk to make dinner, leaving the game on. When I came back, I received a message which made me first think that it's just someone messaging me when I was afk, but when I asked the person via Facebook, they said they didn't go on any riot games that day, and above the message an older date (March 26th, 2021 to be exact). So I was wondering if anyone else has experienced something like this.

P.S. Don't know if this helps, but I can most likely assume this message was a message that was sent to me when I had logged off when the person messaged me on March 26th, assuming this is an older message.
