Yep, I've been having this same issue, amongst others. Today (12/9/2019) was the first day it has crashed repeatedly (5 times and counting). Other than the crashing, the two biggest issues I've had with the app since iOS 13:
- The app routinely "forgets" all the episodes that have already been downloaded (it shows the "cloud"/download icon by the episode) and takes a minute to remember that they have already been downloaded.
- Handoff to HomePod has become shambolic. Half the time, it doesn't keep track of where in the episode I stopped playback on HomePod, but instead resumes on the iPhone from the point I initially handed off to the HomePod.
I suspect it is a memory issue; I think the app is using too much memory, forcing it to page data, or perhaps it is suffering from a buffer overflow bug. Perhaps both.
@Apple, this really shouldn't be a hard fix. Given that it seems to be a widespread problem, why has it not been addressed yet? Wasn't iOS 12+ supposed to be all about stability? Given all the other issues with iOS 13, the company really needs to take a hard look at its QA operations.
