Hi there, there are a couple of threads with a similar problem, but the solutions doesn't seem to be working for me. The folders of all the Apple-apps (Pages, Numbers, Preview... but also Folders of third-party apps like Scanner Pro by Readdle) are not showing up in my iCloud Drive. The only folders and files are the ones I created myself. Also, if I try to locate, say a Numbers spreadsheet via Numbers itself ("open document"), Numbers tries to find the the Numbers folder in iCloud Drive but then there is the annoying "iCloud Drive configuration...."-screen which never ends - I even let it rund over night. Turning off iCloud in the Settings > Reboot > turning iCloud back on seems to fix the problem, since El Cap starts to download all the files again, but after a couple of hours the files are gone again and I would have to do the procedure again. I also tried to reset my wifi settings (read that it might help --> nothing!). Weird thing is, on my iPhone, iPad and on iCloud.com all my files show up. I am using a MacBook Pro (early 2011) with El Cap (10.11.1). Does anyone have the same problem or an idea how to fix it? Thanks in advance!
