A Microsoft file hosting and synchronization service.
What has likely been overlooked is that the Android app may not have finished syncing Personal Vault content yet, even though the rest of OneDrive is working and new scans are uploading.
Try this end-to-end path:
- In the OneDrive Android app, open Personal Vault and unlock it.
- Make sure any files recently added to Personal Vault are fully closed on other devices.
- Wait for sync to complete before checking the Android view again. If there are larger files, this can take longer.
- On Android, open profile picture/icon > Settings > Personal Vault > Auto-lock or Inactivity lock, and increase the lock duration so the vault does not relock before sync finishes.
- Check again inside Personal Vault after sync completes.
Relevant behavior to keep in mind:
- On mobile, Personal Vault appears in the folder list.
- Personal Vault items do not appear in search results.
- Personal Vault on mobile automatically locks after 3 minutes of inactivity by default, but that duration can be changed.
- If the app asks to set up Personal Vault on a new Android device, that setup connects the device to the existing vault; it does not create a separate vault.
If the Android app still only shows Tap to add files after waiting for sync to finish, this matches a reported mobile app behavior where the vault may refresh improperly at first and then start working again after more time.
