Nice, Everything looks fine!

Episodes won’t load/play beyond a certain point in my webbrowser (in my case Chrome). Therefore I can’t jump to a certain point (can’t exactly tell you where this is) within one episode. Same with chapters. However, it seems like I can listen to an episode from start to finish if I don’t skip parts within that episode. I can manually download an episode without issues.
I don’t know where that issue came from. Everything was working just fine until now.

I’m using the V3 of the webplayer. Going back to V2 does not help. I’m on Windows 10 64bit.

The behaviour is different on other devices. I do not experience this issue on my iPhone (Chrome and Safari for iOS). I do experience the issue on a Samsung Galaxy S3 (Android).

Any ideas? Can someone verify this?

Update:
What I’ve just found: The loading process continues as soon as I press the stop button. That way I can force the whole episode to load completely. As soon as it’s fully loaded, I can skip to wherever I want to. Weird.

Update 2:
It does kind of work on Android. It just takes ages to load and play (multiple minutes).
