The secure upload page asked customers for “photos, receipts or documents” while only accepting photographs. Anyone who tried to send a receipt as a PDF was turned away, at the point in a refund where being given the wrong instruction is least welcome. The page now asks for a photo of the item, the damage or the receipt, and says so consistently — and the upload symbol is a proper icon rather than a character that rendered differently on every device.
In your dashboard, the Proof & evidence panel had no inside margin at all, so its heading, the recipient box and the Create upload link button sat hard against the edge of the panel and the button looked cut off. It is spaced properly now.
The guided tour was also appearing on top of any dialog you opened, covering part of it. Dialogs now sit above the tour, and confirmations still appear above both.
