I think bouncing mean short jumps between the strokes and before stroke.
I guess the bouncing might be a problem, when you bounce only for bouncing.
In the international trainings exists different position how good is bouncing.
I see some girls that bounce ever, but think about that:
In the moment when you jump up, your opponent play the ball - you have to come down and then change the direction an move there.
That seems in some situation to much complicated.
I guess you, that you do 3 things:
1. Train your footwork without ball - this means train that you can do all necessary steps for table tennis. Use shadow training for that - means you imagine what happen and move right for the situation.
2. Train your footwork with ball - like falkenberg or other practice - your footwork should work automaticly.
3. Train anticipation - this is the hardest part of practice. You can try the multiball with some regulations:
- you know allways what happen - like Falkenberg
- you know the first 2 balls what happen and the third ball is free
- completely free multiball - very difficult
But you should have your attention to a good multiball coach, he/she should know what kind of balls can't combine. Example: when you play a very good forhand in forhand - in 80% you get a forehand ball back - this is a part of anticipation and tactics - you should learn how the balls fly

.
Whenever you know which is the most likely answer to your ball, you can move easy to the right position and make the point.
