0.4 seems to not work on my device. Keep getting an "App not installed" error. I have enough space available, but nothing I do clears the error.
I have run into this issue before, it usually happens due to a code change that is incompatible as an "update". Usually uninstalling the previous version and installing the new one completely fresh does the trick. This'll delete your saves too, of course (which sucks), but it should install correctly after that.
