Works for me, build #33 (iPhone 6/8.4.1).

Have you updated to the latest build on TestFlight? What device? Any other steps to reproduce?

Same hardware and SW version as you.
I am making a bit of progress. The first two tiles always launch the articles when I try to scroll. Scrolling on their page is really hard then and the performance on my end is pretty bad. Just opening the first article and no reaction to any scrolling on the article page. I have normal fingers with human skin, no gloves and not using anything (pen etc) else to scroll.

Oh I bet I know what you're running into as I can reproduce myself, you're initiative a scroll from within a video div block.

E.g, http://www.theverge.com/2015/8/13/9144397/samsung-galaxy-note-5-price-release-date-specs-video initiate a scroll from within that top video where it says 'Discover' and it won't scroll down.

Stephan, I don't see Safari doing this. Is there something we should be doing here?

If you don't see that 'Discover' overlay on the video, tap play and back out and it appears.

I don't know if this is what the reporter sees but I can reproduce this which might be a different issue?

I'm able to reproduce it in the Discover overlay you mentioned. Not sure what could be going on in this case. I do know that divs with overscroll soak up touch events which prevent you from scrolling if you've started to scroll horizontally for example but I'm not aware of any issues with video divs. We'll need to investigate this further.

I dont see that problem anymore (for now). Was it fixed?

Doubt it. The player was likely cancelling interaction events associated with scrolling. This bug needs a test-case showing the problem in comparison to Safari. From then, we can dig into what we are doing differently if anything.
