I don't know.  I have never used Cash App.

Can any stackers confirm or deny if Cash App will let you pay in BTC but convert to Fiat for customers?

Is partnering with Cash App Pay related to bitcoin, other than you can buy and send bitcoin in the same app? Can you pay with bitcoin? Do you get bitcoin rewards? If not, most people that use Cash App don't even touch the bitcoin features or know they're there.
