No, you cannot download a Cloud CVR recording.
Unlike other cloud events or local event recordings, Cloud CVR records continuously. There is no function to download the entire recording within the Wyze app. That would be up to 7 days of video footage (read: an absolutely massive file!).
You can always view the footage (up to 7 days) on your Wyze Cam and Multi-Cam timeline (Events tab) in the Wyze app.
