Never was a problem for me.
The mean old lady piano teacher would have me do exercises where I held my fingers tips on a table, palms off the table, so only finger tips are touching. Then move each finger up and down individually. Can't move any other finger but the one at a time. Try it. It is hard if you have never done it. Before, especially your ring finger.
Lots of exercises like that to improve hand control.
She would also hold a book under my chin so I couldn't even see my hands and I had to read the music. If I tried to look down I still couldn't see my hands because the book blocked my view.
