What happened to this app – Amex Business Review

I have been using this for almost two years. I’ve never had an issue with it until about two months ago. Now it will not attach a receipt to a transaction. I’ve tried it on android and iPhone, called the help desk and they asked me why I wanted to use it for matching my receipts. Really?! Isn’t that what it’s supposed to be for? They had me uninstall and reinstall it. It worked one time and back to the same error message. It is worthless now. Not worth logging in to even try it.
