No synchronization between app and website?

I'm a new subscriber to dropout and my biggest problem so far is that the synchronization is pretty bad. I like to watch the D20 shows, which lasts about 2-3h. I've noticed that my progress on a certain episode is not saved across all platforms. It's getting pretty frustrating since I've gotta look for the part of the episode i was listening to sometimes more than 2 days ago. I've even noticed that the website doesn't save my progress between different devices?

Is it a known problem? Are there any solutions to this problem?
