Do you keep iTunes podcasts when download them?
By default, iTunes does not keep podcasts when you download them. After you listen to a podcast, it is automatically deleted from your device to make room for new content. However, you can change this setting by going to the "Podcasts" section of iTunes and clicking on the "Settings" button in the top right corner of the window. In the "General" tab, you can select the "Keep podcasts" option and choose how many episodes you want to keep on your device.
