I have an Apple Watch Series 4, LTE. I have many, many, podcasts on my Apple Watch that I listen to when I go for a run. For weeks now the old podcast episodes that I have listened to on the Apple Watch are labeled as "Played" on the Apple Watch. No matter what I do, no matter how long I leave the phone plugged onto the charger with my iPhone sitting right next to it, the listened to episodes are not being removed from the watch and I have not discovered a manual way to delete them. Has anyone experienced this? And if so, have you found a solution?
