Thanks for getting back to us.
Since you’re still unable to see the shared note in the OneNote for Android app, we’ll then try other options.
First option:
Check if you’ve received an email when the notebook was shared with you. If yes, you may sign into your email account via https://outlook.live.com/ or through the Outlook for Android app, then look for that email and click Open in the body of the email that should route you to the app and access the shared notebook.
Second option:
Sign into your account where the notebook is shared to via OneNote Online from the browser of your Android device. Once you see the shared notebook under the list of Shared with Me, click on it and you should be prompted an option to use an app to open the notebook. You may select either OneNote or OneDrive, then it should already open the notebook accordingly.
