Is there a bug report feature which can be used to report bugs with any app hosted on Google Play?
I'm thinking that most developers will welcome feedback on their apps, so would expect this mechanism to be built into the Play platform; or at least for a service to be available for this purpose.
I've found options to report issues with Google's own apps / the Play platform itself, and obviously some apps have built in a feedback feature, but for many I can't find any way to feed back to the developers.
