What should a user check if a shared map in ArcGIS Online is not visible to intended users?

When a shared map in ArcGIS Online is not visible to intended users, checking the permissions settings for user accounts is essential. The permissions determine who has access to view or edit the shared content. If the map is intended for specific users or groups, verifying that these users have the correct permissions is crucial for ensuring accessibility. Permissions can be set at different levels, such as individual user permissions or organizational settings. If the permissions have not been configured properly, even if the map is shared, the intended users may be unable to see it.

While factors like network connectivity issues and layer visibility settings might impact access or display of the map to some extent, the primary concern for visibility is how the permissions are established for users. Data storage size limits, while important for managing content, would only affect the ability to create or upload new data rather than whether a shared map is visible to users. Therefore, focusing on the permissions settings directly addresses the issue of user visibility.
