Receipt snap isn't working

I have taken a photo of the receipt in the app, once I take the photo it usually says extracting info then leaves the receipt in the for review section for me to manually review the receipt and then create an expense from that receipt once I have reviewed and saved it. The problem now is that when I take the photo of the receipt it says extracting info but when I click done it disappears and there's no trace of it in the 'for review' section or in the 'reviewed' section, nothing in my expenses section either.
