After connecting Screencastify to your Google Drive (highly recommended), every recording you make will automatically be saved to your Google Drive in a folder called "Screencastify".
Once a video has been uploaded to your Google Drive, the progress bar will disappear. While you wait for the video to be uploaded, you can copy the shareable link.
This process could take a few minutes, depending on how long your recording is.
Important: if you delete a recording in Screencastify, it will also be deleted from your Drive. If you move a video out of the "Screencastify" folder in your Drive, you will no longer see it in My Recordings in Screencastify.
NOTE
Your recording may appear blurry in your Google Drive immediately after uploading because Google processes the low-res version first. The full-resolution version of your video will be available within 15 minutes.
