Gulp watch - dropbox folder

Hi, I have noticed an issue with gulp watch and livereload.

I moved my ionic 2 project to a dropbox folder on my Mac, and livereload no longer works. It looks like an issue with gulp-watch.

on ionic serve, gulp watch takes about 30 seconds to complete. The projects serves up ok, but making any changes doesn’t show in the terminal. Shifting the folder out of the dropbox folder solved the issue, but I have to use dropbox for this project.

Has anyone come across this and managed to fix it?
