Apple Podcasts only shows latest (one) episode out of 10
Hi, would someone help me to understand why Apple Podcasts is only showing one episode (the latest, called Episode 10) instead of all of them. I've checked the podcast using https://podba.se/validate and https://castfeedvalidator.com, also submitted to Spotify and see all 10 episodes.
The feed is:

Any help would be greatly appreciated.
