I cannot get onenote android app working. It's stuck on the loading screen right after logging in; it says "Getting your notes." It never goes past that. The most I've had patience to observe has been 40 minutes. I tried uninstall and reinstall several times. The phone is Sony Xperia Z3 Compact, Android 5.0.2, build 23.1.A.1.28. However, before upgrading to Lollipop, the Onenote App had the same problem with on Kitkat (Android 4.xxx). There is plenty of free space on the device. The notebooks are stored in onedrive and the synchronization works fine with other devices (PC, web app, ipad, previous android phones...) Please help. I've been using Onenote since the 2003 version and it is an indispensable tool for me.
