Hi,
We’ve updated our security in accordance with Apple. 
Apple have identified a bug which they’re fixing, here is a work around for your receipts http://goo.gl/8bnfHR 
We’re currently working on a new version of our app to be released very soon. 
Sorry for the issues but it’s a bit out of our control. We’ll let you know when the new app is released. 
Thanks Pete
