I also lost approx 500$ or more in that. I didn't do anything in DLUX. I invested my efforts time & energy in building 3Speak mobile app. That too I had to take it down from appstore & playstore because meno did a lot of changes recently on 3speak resulting into mobile-app non-functional app. I asked him to just raise a PR with set of changes, source code is open any way. But he is busy guy & may be not interested in 3speak mobile-app. Hard to see things dying in front of your eyes. but it is what it is.
