Create Podcast Seasons in Seriously Simple Podcasting
To separate your podcast episodes into distinct seasons you can use the iOS11 custom podcast fields within Seriously Simple Podcasting.
By default, these fields are disabled but you can enable them by going to Podcasting > Settings > General.
With this setting enabled, you will see extra meta fields when creating/editing an episode. Some directories, like Apple Podcasts, use these values to assist with organizing your episodes on their platform. Seasons and Episodes numbers must be a non-zero integer. So 1, 2, and 3 are accepted but 01, 02, and 03 are not.
