Pages on iCloud really slow!

I am using Pages on my iPad Air, and have quite a few files..maybe 600. Pages on my iPad seems to suck my iPad's battery, as it's used 62% of my battery ife this week, which in a pretty new iPad Air means I can go from 100% to 20% charge in about 6 hours of use, while plugged into a Windoze machine's USB outlet, where it gets at least a trickle of electricity (I get the green battery icon, but still see the charge zooming down). So I am guessing I can improve this by cleaning out my older files.

But that's not what my question is: I want to bring up my Pages files on iCloud, I can then look at FileApp (onto which I archive my files) on my iPad and then delete files in Pages once I confirm I didn't miss any file in archiving.

However, using MacBook Pro running OS X 10.11.3, I can bring up iCloud in either Safari or Chrome, click on Pages and....well, I get nothing but the message "Loading" and a spinning circle for longer than I have patience for, at this point well over an hour. My internet connection is DSL and running fast enough, and my Wi-Fi signal is just fine from my Airport Extreme.

It's my impression that I may not be able to access my Pages files on iCloud. Is anybody having any luck with Pages on iCloud?
