No tile appears I installed the app on my Nexus 6p on build NRD90T and went to the notification shade  nothing. Read through the comments and someone mentioned you had to run off adaptive brightness for it to work  so I did that  and still nothing. I even tried uninstalling and reinstalling it and still nothing  the tile never appears. I'll leave it installed for a bit to see if it gets resolved  but so far this is a useless app for me.
