The “Report a Problem” link in the App Store just reports it to iTunes support, so skip that for now. Instead, open iTunes on a desktop system and search the iTunes Store for your broken app. Click on Ratings and Reviews. Just above customer reviews is App Support. Tap on this and you’ll often find the quickest method to reach out to the developer.
