Naps / changes to sleep

Hi all. I have a 2yr8m old. She has recently started pushing her wake windows out - so had gone from going to bed at 7.30 (with a nap around 1-2 or even 1.30-2.30) to now not going to sleep til at least 8.30. the last couple nights been 9pm. We are doing 1-2nap or if she falls asleep earlier then cap at 1hr. Sometimes she will skip nap and thats fine, she goes to bed at 6 on those days.
the later bedtimes are not great, especailly condsidering she ahs suddenyluy decided she wants me to lie with her til she goes to sleep, so it just feels like my evening is gone now. Shall i alternate days and purposely do a no nap day every second day? at the moment it feel if shes is sleeping at 9pm, i wake her up next day and shes a bit grumpy and then ends up napping?
Idk! advice? or just ride the wave ?
