This thread has become quite long and confused - I'm not really clear on whether the report is about the Chrome Web Store, or Google Play. As of recent builds I made some changes and collaborated with Kyatric who was testing the publishing side, and it was a bit fiddly to set up, but worked. Kyatric's tutorial covered the setup to help others get it configured the right way. So as far as I am aware, it is working and documented. Given these changes since this post was originally made, and the lack of focus in this thread, I am closing it and recommend to file a new report (again following all the guidelines as closely as possible) if you are still having trouble. I would also recommend making one report per store, so there is a clear focus in the bug report, e.g. one report for any Google Play issues, one for any Chrome Web Store issues, etc.
