DPS single-issue apps with iOS8 — any issues?

My (published) iPad app seems to be having issues with iOS8. I just upgraded to the GM os iOS8 and my app has serious issues, crashing quickly after moving between a few articles. I've seen the advisory about multi-issue apps, but this is a single-issue app. There are HTML ads in the app, built in Tumult Hype, as well as scrolling frames, video, and zoomable maps, but I think the HTML ads are causing the issues. Here's the (free) app if anyone's curious to try it:

I'm going to update the viewer to the latest version tomorrow to try to fix this, but before I do, are there any known issues with Web Content views? Most of the crashes seem to be after an ad tries to animate, which would seem to point to a memory leak in the HTML playback engine — but it could be another issue. Has anyone else had problems with their single-issue apps?

Thanks in advance.
