Your mobile device records and uploads your track during the recording session.
If you exit the Riverside app before your local recording has finished uploading, your audio/video data is still on your device.
Relaunch the app, leave the app open on your screen, and your upload will resume.
IMPORTANT:
Do not uninstall, delete, or log out of the Riverside app before the upload finishes. This will delete your recording data and it cannot be recovered.
