As a lifetime supporter I'm very sad to hear that since upon hearing you're developing an official app for Tizen series I've expected it to be for 2015 too. My main died the week before Christmas so when that happens you don't really wait for the next get to come out, you buy what's available.
There are many happy users with the existing app on the 2015 models and the app does support the 2015 tizen models in emulation mode. If you do have problems then there may be ways round them and there is a lot if help on the app forum . Sorry I have not checked your past posts to see what problems you had.
