It often happens that I create a Pages document on my home laptop, upload it to iCloud, then want to download it from iCloud at school. For some reason, iCloud doesn't support this—I need to, at some point between those two steps, open Pages on an iOS device synched with my iCloud account. Then it'll work fine.
I assume this has something to do with a preview being included in the file, as in iCloud it shows up as a generic .pages document rather than the customary document preview image thing, but I can't see why. Pages does include a preview in its saves, and "Include preview in document by default" is checked.
What's happening, and is there any way I can get around it without use of an iPad or iPhone?
