Marshmallow upgrade deleted my audio files (audible, doggcatcher)

I upgraded my Android phone (HTC One M9 on Verizon) to Marshmallow this morning. When I went into the Audible app, all the books I had downloaded were available in the cloud but no longer in my device library. The same thing seems to have happened with audio files from my podcast player (Doggcatcher). Interestingly, it appears that my pictures were not deleted.

Any idea on how to get my audio files back, short of re-downloading them all?

Thank you,

Ben

OK. I got the same problem on LG G4 Verizon. After I upgraded to Marshmallow, all my downloaded audio books are going from MicroSD.
The worse thing is under audible setting --> Download option --> I no longer see "download to external SD" option. I can only download it to the phone memory.
