If an app restart doesn't work, the next step should be to conduct a soft reset or restart on your
iPhone X. A soft reset or device restart is a highly suggested treatment for minor software problems and issues. You don't need to back up your iPhone data because it won't affect any of your other devices. This procedure is likely to resolve random system faults and small app troubles. Here's how to perform a soft reset on your iPhone X:
1. For a few seconds, press and hold the Side/Power button and either Volume button simultaneously.
2. Release the buttons when you get the Slide to Power off instruction.
3. To turn off your phone, slide the Power switch to the right.
4. Press and hold the Side/Power button for around 30 seconds, or until the Apple logo shows.
When your iPhone X has fully booted up, launch Netflix again and see if it’s already working properly.
