PLEASE add the ability to enter podcasts by URL. This is a standard feature in just about every other app that plays podcasts. It's the only way those of us who subscribe via patreon or other sites to listen to our ad-free RSS feed provided to us via URL by the creator. This has been misinterpreted several times by Spotify as users asking for their favorite artists to be listed. This IS NOT that request. Please understand what we're asking for. It's almost embarassing that Spotify can't do this in 2019.
This is a feature that has been requested by several hundred people each year, and for some reason it's denied by Spotify because they don't think enough people care to add this feature. Apparently, we in the community must ask this question repeatedly, annually, and hope that we get enough upvotes for Spotify to DO anything about it.
