What you need to do is refresh the podcasts at a time during the download period and then set the update podcast to "Daily"


Find the settings button :-

![settings][1]

And select Daily..

![Podcast refresh times][2]

This is because the Daily refresh will reset itself to download every 24 hours after that time..

As seen here I refreshed this morning and the next update will be 24 hours after that.

![Refresh time][3]
