There may be several reasons for this:
- Perhaps your connection has been temporarily lost. If possible, please try another connection.
- If your device has limited free space, the card cannot be saved completely. Go to your device settings and check your available storage. Remove unnecessary files or apps and try again.
- Sometimes a download may become "stuck" due to a bug or temporary issue in the app. Stop the download, close the app completely, and restart it. Remove the map and try downloading again. Also, ensure you have the latest version of the app.
