I have previously complained about PayPal disabling cut-and-paste for password entries. Apparently, this is also the case for the destination entry, when sending money without an invoice:
That "Email or mobile number" field up there? The one where one typo can result in your money being gone forever? Yeah, cut-and-paste didn't work; you have to type that shit manually.
Sometimes I wonder if they're not deliberately trying to drive me insane.
(Actually, the part that pisses me off the most is that my own browser obeys to this stuff.)
