Anyone dealing with late bedtimes and long wake windows?

My little girl has always been a later bedtime baby, never been a 7pm girl- 8 or 8.15pm worked well as she slept til 7.15am and I dont start work until 9.30am. This week she hasnt been to bed before 8.50pm 😵‍💫 Even today though she only napped 1.5 hours. So its not like she is sleeping late in the mornings or having excessive naps, and she would never nap past 2.15pm at the latest. Couldnt cap her nap by much anyway as she would be so grumpy plus nursery dont cap them anyway. Any tips? Ps she sleeps all
