Yeah, I got the same thing. it failed as soon as I accepted and confirmed my address, because apparently thats just how my luck is going this week. Thank you so much for trying, honestly. Genuinely its deeply appreciated that someone would even try.

hey, having spent the day in chat with cashapp support, if you want to try again they claim it should work. I had to create a new account and redo everything, so it's £4pennycoffin

no worries if you don't want the hassle.
