Podcasts on Apple Watch: Getting the latest episodes

Hi,

I am trying to get my watch to sync the latest podcast episodes I have selected on my iphone (Iphone>watch app>podcasts>custom...then I selected all the shows I want to sync).

The watch does sync the selected shows, but NOT the latest episodes (which is what I want).

It seems to get tripped up if I listen to part of an older episode downloaded onto my watch. Here's an example: a podcast I listen to has released episodes on the following dates: 5/4, 4/27, 4/20 and 4/13. The 5/4 episode is not on my watch as a download (despite the fact that today is 5/7 and I've sync'd multiple times since then). But the other 3 are. I think this is because I'm half way through the 4/13 episode - which is why I say the sync gets "tripped up" - it doesn't want to remove that episode until I'm done - which I dont care about).

So again: How can I get the latest podcast episodes to sync?

If there is no other option: I'm thinking maybe I can completely remove all podcasts from my watch every so often and resync - does anyone know the best/fastest way to do this?

Thanks,

Max
