I closed the page or only heard the start of a dialogue. Should I generate it again?

Check the original task first. Open History for a reading or dialogue you already submitted; text that was still in the editor is not a submitted task. On desktop, a dialogue preview can play before the full audio is ready. Wait for the full result to download it. If the original record says the audio was saved and offers to retry processing, use that action there. Pending billing does not mean the task was free or refunded.
