I’m typing on my Google Pixel phone (so it’s Android). I text a rainbow of hearts to my kids each morning as a sign of life, so they’re always in my recents, whereas the squares are way down the scroll of emojis. Then I double-return between rows because it doesn’t seem to format a line break otherwise. It came out as 4 rows of 5 yellow, gray and green hearts to me. Are you getting gibberish?
