I am having the same issue. I have uninstalled and re-installed both SkyDrive and OneNote more than once.  I can access the notebooks from my PC at work, which also has OneNote installed, but not from my android phone. 

Previously I was easily able to synch my PC, my laptop and my iPad over my home network. Now I cannot do that either. One day I opened OneNote on my iPad and everything was gone. I thought it might have to do with installing it on my android phone.

I love OneNote and do not want to switch to any of the other programs. I have a lot of information stored there but I need to be able to access it on the go without having to lug my laptop with me.

What can I do?
