How to cancel a recording or upload made by mistake

1. Right after you stop a recording or upload a file, the meeting shows Starting in … s in the Meetings list. A recording waits 15 seconds and an uploaded file about a minute.
2. Tap Cancel before the countdown ends. Nothing is charged.
3. Already processing? Tap ⋯ on the meeting's row, then Cancel and delete, and confirm. It is stopped and deleted, and nothing is charged.

Once a meeting has finished processing, delete it the normal way.
