It works fine in the simulator, but when I go to put the .prg on my actual watch it just deletes itself. I have looked all over online and people say this happens if it isnt signed, but in my case it is signed with my dev key. Does anyone know any other reason why the .prg file is getting deleted everytime and why the app wont show up in my activities? Please let me know if more information would be helpful. I am on ubuntu, not sure if that would matter, it seems like an issue with the watch, not my OS.
