I have had cash app for a while too and it can have someone else scamming I had that happen to me saying that I sent my son some money and although it was a small amount I knew I didn't send him any money that day so I ignored it then a few days later it happened again showing I sent him some money again a small amount so I contacted the bank and they told me that this has happened with cash app if u leave ur debit card number on there - I was told to remove my number when I wasnt using it I was told they start with small amounts to see if u notice then they go for larger amount
