[EDIT: Garmin fixed this within 24 hours. Re-install the Spotify App on your watch]
This has been tested with several users, all experiencing the same issue. Some Epix, some Fenix.
I select SPOTIFY > ADD MUSIC AND PODCASTS and the select PODCASTS
I can see the main thumbnail of the podcasts I am following. But when I click one one I just get the endless spinning graphic that makes it look like it is loading the episodes but never does.
I am able to update Playlists AND I am able to upload a playlist that contains a podcast. The podcast works. I just can not access the podcasts via the correct Podcast menu,.
I have uninstalled and re-installed both Garmin IQ Store and also the Spotify App. Watch has been turned off and on and also been factory reset.
