Pages documents won't open or download
I have a few documents in iCloud that suddenly will not open on any iOS device or download through a browser on a Mac. I created these documents a few weeks ago and have edited them several times, not all of the sudden when I click on the icon on an iPhone or an iPad the icon flashes but it doesn't open, and when I try to download them with Safari I get an error saying they can't be downloaded.
What is going on? How can I get to my documents? As I am sure you can imagine, these are important files that I need to be able to open. Hours and hours of work here that can't be easily reproduced.
