If there was a third party app to control the nanoleafs, I'm pretty sure everyone would have jumped ship by now. I always expect to close the app the first time and reopen it because of the constant connection issues. No restart and anything you do will probably fix it. Yes, the scenes are awesome and you can download and customize your lights to your heart's content but man...all we want is to not see the 'cant connect to nanoleafs' everytime we open this app. Update 2022: Still unusable
