@zero0cool Your best bet would be to contact Uphold to find out what they might need. It’s not always easy to find on their website. Definitely is an area they need to improve. But if you write in to ask about their KYC/CDD/AML process, in particular Liveness. Let me share where someone else kind of explains about it after they went through a similar experience.
If you have Android, a lot of people are saying the process works better there. Otherwise you’ll need to go through either support@uphold.com or create a ticket via https://support.uphold.com/hc/en-us/requests/new if having issues finding anything in your account.
