I have not mastered it by any means. Advice is to be patient. It takes how long it takes. Watch Jonathans YouTube video. It helped me a lot. Play the C to F chord change (Jonathans suggestion). That helped too. Did I mention to be patient.
Playing 1-1/2 years.
You have to learn to play that chord. Jonathan has some tips. I learned the 4 string F (with a min barre on the B and E strings). I didn’t bother with the F that engages the pinkie and the mini barre because I was able to master the full barre chord F with lots of practice.
The 1, 4, 5 in the key of C requires going from C to F. Keep trying, or use a capo and play in the key of G or D to avoid the F while sticking with open chords.
