I agree this is beyond disappointing. The Windows 10 version is still a joke. Something as basic as section layout wastes a huge amount of screen real estate. I can see half the teachers at my school dumping it tomorrow for that fact alone. None of us at my school have seen any of this purported reliability as well. The OneNote app crashes all the time on many different types of hardware. OneNote on the desktop has been rock solid for us. I'm normally the first to embrace change but this is sad sad sad. The integration between OneNote Desktop and Outlook is far superior than that of the app, because you start your notes from Outlook, my users love that. One of the most popular features built into OneNote for the Desktop is the Send to OneNote Printer. It's not even part of the app, unless you download an add-on from the Windows Store. Exactly 0% of my users will even bother trying to figure that out and that's just about how many have Windows Store accounts in the first place. The immersive reader in the OneNote app sucks at best, this is a must have feature for Schools. It works beautifully in the desktop version, the last thing we want to do is place more barriers in front of students who struggle with these tasks, but that's exactly what the app is, a barrier.
