Definitely give it a few days to settle. My DS had really high sleep needs, and still sort of does. It used to take me a solid week or two just to extend his A time by 15 mins! Now it's much easier to push him through but if he's had a really busy day, he'll crash a little early.
I find taking my LO out for a walk is really helpful to extend A time without getting him all wired up. Also, sometimes he only naps for an hour, sometimes he crashes out for the full 1.5. It really depends on the day.
I would work on gently extending her A times, have a solid settling routine and see how it progresses from there. I have set nap times, which you might like or you might not. 10am and 3pm is nap time in our house and I found it way easier to plan my day from there. I hope this helps a bit.
