Hi Dan,
This issue happens because Sticky Notes integration relies on Microsoft’s cloud sync and app updates. If the tab isn’t visible, it’s usually a version or rollout delay not something you did wrong.
What You Can try is:
Update the App
Check the Play Store to make sure OneNote is fully updated.
Verify Account Sync
Confirm you’re signed in with the same Microsoft account that has Sticky Notes on Windows or Outlook.
Access Sticky Notes via Web
Go to https://onenote.com/stickynotes in your mobile browser to confirm your notes are there.
Use Microsoft Launcher or Outlook
Sticky Notes often appear in the Microsoft Launcher feed or Outlook Notes section if OneNote hasn’t updated yet.
Wait for Feature Rollout
If everything checks out, the missing tab may be due to a regional rollout delay.
Let me know how it goes, Happy to help!
