I got 2 messages from unknown people today with a down arrow in an open box. I blocked both phone #s. Then I got the same icons from 3 friends. I clicked on the 2 down arrows from 1 friend. It immediately opened and showed her as sending a GROUP message that included the 2 people that I had just blocked! I didn't touch the arrows in those 2 that I previously blocked. Even though I blocked them, it obviously did something for me to get messages from 3 friends with the same down arrow in a box. Now I have just gotten another text from another friend in that group of 4 with nothing but the down arrow. So, what did I unleash by clicking on that down arrow in the box? And why would clicking on that down arrow immediately send a message from that friend when it could have been sent without the message not being able to be sent unless I clicked on the down arrow? To me, it had to have at unleashed something when I clicked on the down arrow????? Does anyone know what's going on? I tried doing a search on the internet but I couldn't find that down arrow in an open box anywhere.
By the way, when I get a message with the down arrow in the box, all the message says is "Not available."
I have a 4-year-old Samsung Galaxy S20 FE 5G.
