Hello wax049,Thank you for bringing this to our attention. We appreciate that you've taken the time to post your concern here in Microsoft Community Forum. We understand that you’re having trouble creating a notebook in OneNote for Android. Let’s check on this together and find ways to address this matter. Now for us to better assist you on this matter I need to ask the following:
- Have you tried restarting your mobile phone?
- Please consider uninstalling and reinstalling the OneNote app
- Please check for some updates on the Google Play store.
Please make sure when you create a new notebook you named it without using special characters or invalid characters. Please consider creating a notebook and name it as " Test" so that we can check if the issue is with the name you setup or not.
We look forward to your response.
Sincerely,Juhn Jac,Consumer M365 Forum Moderator
