I used to use Spotify on my Fenix 7 Pro. It was always hit or miss, but maybe 75% of the time I could get it to download a podcast and I could listen on my run. Within the last few months, downloading podcasts is permanently broken. It will start to download a podcast, get to around 10 or 15 percent, and then hang. I have to cancel the download.
I also tried Amazon music and Playrun apps, in case it was a problem specific to Spotify. All apps have the same problem. They will start a download, but it always hangs early in the download. Now I'm back to carrying my cell phone on runs to be able to listen to podcasts, which was exactly what I bought the Fenix 7 to avoid.
I have tried uninstalling and reinstalling the apps multiple times. I've tried power cycling the watch. An update has installed since this problem appeared, so there has even been an OS upgrade in there as well.
