How do I prevent an app from using my mobile data? (4G, H+ etc.)

On my OnePlus 5T I was able to prevent my phone from using mobile data on YouTube so it would only let me stream video's from the app via WiFi. This was great from me as my WiFi often cuts off from the third floor of my house and saved me a nasty data use bill at the end of the month.

You can turn Off Mobile Data by pulling your shade down from the top of the phone and tap on this icon >

Just remember to turn it back On when leaving the vicinity of your Wifi.

Daily Driver > Samsung Galaxy s²³ Ultra 512Gb in Phantom Black.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "

You could make a Bixby Routine, that toggles Mobile Data off, when opening Youtube app.
