Between the helpdesk and me, we couldn't work out why verification text messages weren't arriving, which meant I couldn't even begin to use the app. We came up with a workaround to use my partner's phone. As for the app itself, it's mostly fine, but inconsistent; I had the option to upload an existing identity document, but had to take a call, then when I came back to do it that option had gone, and I could only take a new photo of the document. All that said, the helpdesk is that rare thing, responsive and actually helpful!
