Any LC's or latch experts on here?

My daughter has a really shallow latch! It doesn't seem to matter if I pull her off and wait until she opens really wide she always adjusts her mouth to a more shallow latch. It isn't causing me any pain and I know she is getting enough milk, but is it because my letdown is too fast?! I didn't have this issue with my son, he always had the textbook 'eat a hamburger' latch. Any advice on how to get her to open up more would be great 😂 Pics of her latch in comments.
