when I use my volume buttons to rewind, it restarts from the beginning

This works perfectly with my podcast app, but on Waking Up, it restarts the audio instead of rewinding/skipping when I use the volume buttons on my phone/headphones.

Also: whatever happened to downloaded episodes? I really found them useful when I'm offline. Now I can only use the filter if I also save the episode in a playlist, which I don't always do.

Thank you!
