When remote voice tracking, you can monitor the Update Queue section in the Session Controls panel on the right-hand side of the interface. This queue displays all commands being sent to the server, including your recorded voice tracks and any segue changes you make.

If the commands are showing as Processed, this confirms they are being successfully accepted by the remote voice tracking server. It's worth regularly checking this queue to ensure everything is being processed as expected. Before ending your remote session, make sure all pending items in the update queue have finished processing, otherwise your hour may be incomplete. Do not close your browser until all items show as processed.
