The new UI has moved some of my apps randomly into sleep, deep sleep or never sleep mode.
It's not entirely clear to me if never sleep is required for apps that send notifications.
Do I need to put all apps that send notifications or run checks i.e. email, BBC news, one drive, whatsapp, facebook etc etc into never sleep? A specific instance is a fitness app that uses GPS etc and it stopped working after the UI update. Do I need to put it into never sleep, or just make sure it is not in sleep or deep sleep.
