There's a trading reddit that I sometimes visit where they all use Paypal Friends and Family which I gather is incompatible with Venmo despite being owned by the same company? The time or two I've used it, the guys on the other end took Square's Cashapp luckily. I do have Venmo because a former team used it. I also have Zelle because it's built into the Ally Bank app which came in handy to pay back my Uncle when he helped with some fence construction. If this is innovation, I'm pretty tired of it.
