Hi! Welcome to the Samsung Members community!

Can you elaborate? Any error messages? Does it simply do nothing?

Firstly, go to the Samsung Members app > Support > Diagnostics. Does it pass?

Issues after an update may suggest clearing the cache partition on your device. Plug your device into a PC/laptop before taking any steps.
