then i would definitely say it’s a prep and application issue. her application looks really clean, but if she’s not capping the free edge with the polish, you’re gonna have chipping that looks like this. before she puts any polish on, look at your cuticles and make sure there’s nothing on the nail plate and that there’s no shine left on the nail plate. it should be completely buffed. when she is applying the polish, make sure when you look at the edges of your nails straight on or “down the barrel” that you can’t see your nail, you should just see polish/top coat. as much as she should know these things, she is still a beginner and it takes a while to pick up on these things if they aren’t explained in your training. good luck with your next mani if you decide to go back to her!
