Has anyone had success upgrading from a True Money Basic account to an Advanced account, using your DTV info? I've uploaded the requested info (photos of my DTV visa stamp in my passport), as well as the actual DTV visa form as backup; but I got rejected with the message "Sorry, we're unable to unlock the advanced services for you because you submitted a picture of other items rather than a supporting document." Not totally clear to me what else I am meant to provide.
Any suggestions from those who've successfully done this are welcome, many thanks!
