Cadie:
So I have been away from game for about 6 years. At the time I left I had a bunch of different balls in my equipment. Now I can not find them. Do they go away?
You should still have them. In the game app / main screen, click your profile pic (upper right corner), then click EDIT EQUIPMENT at the bottom. Then click BALL on the left side of the page. All the balls you own should be there.
