The risk of people turning them off entirely must’ve been just enough to get them to offer this granularity (as seen on iOS). Not all apps are so kind (grr).
The issue is with the information. Like the one above us said they want to be notified that their ride has arrived but to allow that notification you have be willing to accept advertisements as well.
It's the reason a majority of people just straight up kill notifications. Way to many useless ones to justify the 1 in 8 that you want.
the only issue is that Fitbit requires it's app to be running in the background to deliver notifications, and for some reason it wants to use internet.
