Would benefit hugely from a paired website app for uploading files: having to send and then locate multiple files on(to) my phone to then upload to them (again) to the app while tapping constantly between different screens is exceedingly cumbersome process and wastes unnecessary time for the user I find. The photo / passport identification feature works well enough. Think the phone app could consider a direct scan feature for documents also.

total waste of time. Doesn't recognise face scan even though passp picture is only a year old and I haven't changed at all. It is browser specific but they don't tell you this so you waste ages trying to get it to work. Support is via online chat. Although this works ok as soon as it presents then with an issue they're don't expect you get passed off to tech support where you wait for a response. I wouldn't use this app for such sensitive info knowing how flaky it is. They now have my data🙄

Contains some pretty major oversights, mainly in lack of explanation of terms, lack of confirmation dialogues on significant operations and no multi-file selector. It's pretty miserable uploading 24 payslips, each requiring 5 careful taps, while you keep track of the documents you've already uploaded and try not to click on the submit button which stupidly occupies the same space on screen as other buttons you have to click 3 times per document.
