I think this is where I am to send for help but just recently our host left our podcast and when he did he deleted our hosting website so I had to go around and create a new one how can I change the RSS feed we have in there right now to the new one is that something you guys could do or is there something else?
Unfortunately we can't help you here ......the app depends on publishers of feeds/podcast servers & feed RSS URL's to point the app to those servers in order access & download media files.
Checkout Feedburner - https://www.feedburner.com/ - I imagine you can create a new RSS URL and point it to your hosting website
If feedburner doesn't work...then I would suggest Soundcloud - https://creators.soundcloud.com/podcasting or Anchor - https://anchor.fm/login they offer different services from creating a hosting podcasts and distribution of your feeds.....from only using their apps or to all podcast managers including DC
Also here are few articles on creating your own podcasts
