If you are trying to train your Personal Style and come across an error next to any of your catalogs stating they cannot be scanned, please make sure to check the following:
If your catalog is stored on a network drive (NAS), it must first be copied onto your computer or an external drive.
If you're using a cloud based storage system such as iCloud or Onedrive, ensure that you have all the files related to your catalog downloaded to your computer.
If your catalog files are all downloaded onto your computer and your catalog still cannot be scanned, try to open this catalog inside of Lightroom to check it is still working as expected.
If your catalog is working as expected but still not able to be scanned inside of Narrative, force quit and reopen the application.
If the issue persists and you're using an external drive, try to disconnect and reconnect your drive that your catalogs are located on. If you're using a Mac, Narrative can automatically rescan the catalog and drive. If you're a Windows user, there will be a popup asking you to rescan your drive.
If you're experiencing any other issues or the article above hasn't resolved your issue, please contact support via the chat bubble in the bottom right corner.
