Podcasts

[Olds777]

Are the podcasts I've listened to only linked to the device I heard it on, or to my Spotiify account??
I've listened to dozens of podcasts and one day suddenly none of them showed as Played. Some were downloaded and listened to offline, most were streamed over Wi-Fi. Since then I listened to more and I've emailed support and their troubleshooting has reset them all over again.

Device is Android Samsung Note 5
Spotify version 8.4.1846

I've deleted the cache, uninstalled, reinstalled, restarted the device and talked to 4 different customer service workers trying to figure this out.
