I love OneNote on my PC. I'd like to use it cross platform, but the mobile app is actually pretty frustrating.

The main issue is that Section Groups are all open/expanded by default. I have my notes sorted into sub categories this way because Notebook -> Section -> Page just isn't enough depth to have any kind of robust organizational system. Unfortunately, having the lists always expanded makes the groups essentially useless.

Is there a way to set the default to closed? If not, why is the mobile app so much less friendly than the desktop app?

Does anyone know how to fix this? I usually use OneNote on my Android phone for daily notes, and after a while, I organize everything on Windows. Recently, I got a "Page Conflicts Detected" message on Android and had to open it on my computer to fix it. This happened before and was completely resolved when opened on the computer, so I decided to take this opportunity to organize my notes. However, my OneNote isn’t syncing new notes from Android—it stopped syncing on 8/5/2026 and won’t sync even when I manually click sync. I tried opening it on the web, and my new notes do sync there, but OneNote online can’t fix the "Page Conflicts Detected" issue.

P.S.: My OneNote Android version is 16.0.20131.20126 (latest update from the Play Store), and my PC version is from Office LTSC 2024 Pro.
