I'm having an issue with the podcasts app; last night it said it had to rebuild the library, and got rid of most of my podcasts (not ones saved to the device but the ones on the screen that says my podcasts where it has the ones you've listened to) except for a few of them, and now whenever I go on top charts, featured or search they're just blank screens and the search bar or anything never loads so I can't search for new podcasts or get my old ones back. I tried signing out of my account in settings and signing back in but nothing changed. I was going to delete the podcast app and redownload it but I checked the App Store first and I couldn't find it anywhere to redownload it when I delete it; it wasn't in my purchased and doesn't come up when searched.

any help is appreciated, I use podcasts a lot.
