Hi Winston,
So I've reset my devices and been able to delete all the documents from icloud (web). But when I now switch on Documents and Data (only on iPad so that only device is syncing for now), a set of documents pop up on iPad all showing sync errors (pages and numbers icons representing documents with blank progress bars, or blank documents with progress bars that don't open or update and so forth). The app says "Updating 15 documents..." but after a while the app is willing to open new documents but no updates happen. And soon after this the up arrow (waiting to sync) icon appears on the document in both Pages and Numbers. And finally, the progress bar will appear, move some part of the way and then stop. And then the app works but doesn't sync any further.
To re-clarify, my icloud (web) account only shows the coloured icons for the new documents (as opposed to a "live" icon with text or spreadsheet items in them) and no other documents at all. I've created precisely one document each on iPad and these are the only ones on icloud. But on the ipad there's all those other documents that pop up.
I've got everything backup so I'm not worried. But in this instance, "it just works" isn't happening. Please help.
Below is the icloud web screenshot (chrome/Windoes) and then the ipad screenshot (iPad 2, 64Gb 3G, 5.1.1). The first document (Hayate-DreamY-Splendor) is the only document that should be there on both. The rest are officially deleted (do not appear on web, on the icloud settings page etc).
