Why is Play Store still asking for all app permissions on install on Android Marshmallow? From everything I've read, when installing a new app from the Play Store under Marshmallow, it is supposed to just install with no permission questions (e.g. Slash Gear article). The app is then supposed to ask for each permission it needs as you run it. 

This is not happening on my Nexus 5 which I updated via OTA to 6.0 earlier this week. When clicking install in the Play Store, still getting the massive list of permissions along with an Accept button. Is there a setting that is needed to make this work as expected?
I believe the app has to be made with API 23 (aka Marshmallow's API) and the user has to be on 6.0 Marshmallow or higher for what you want to take effect. However, you can still go into Settings - Apps and change each app's permissions individually, or go into Advanced under Apps (the gear icon) and change them by category.
