Hi Tim Rodman,
As far as I know, this alert message is pop-up when we encounter the following scenario:
- In a Microsoft SharePoint Online library, you click Library Settings and then click
Versioning settings.
- For the Document Version History setting, you select
Create major and minor (draft) versions.
- For the Draft Item Security setting, you select Only users who can edit items.
- You click SHARE, click Get a link for a document in the library, and then click
View Only Anyone with this link can see this file.
- You share the link with a user, and the user browses to the URL for the shared document.
To work around this issue, take one of the following actions:
- Publish the affected document.
- Change the Draft Item Security setting to Any user who can read items for the affected library.
