"Reach out to us and we will fix it manually" at the customer scale of these hosting companies sounds like Spotify either didn't think this through fully or didn't take it seriously. Idk.
The wording on that Podigee dialog box left nothing to the imagination on that choice being a one-way street, so the hosts clearly believed that it wasn't solvable and were willing to put out a scary message to their customers which I'm sure they hate to do. What a mess.
