iCloud syncing stuck at "updating documents"

[Loa]

Hello,

Have been using iCloud on my iPad for a while, and now it seems stuck when I use Pages for iOS. iCloud works well with other apps, but not with Pages.

I have about 60 documents in the cloud, and most of the, work, except that some have the greyed icon with an empty progress bar. I tried removing iCloud, reactivating it, but it doesn't work. Some files, at random, jist won't update.
