Anyone going through the 11 month sleep regression?

My daughter went from a great nap schedule to refusing to nap at naptime, getting overtired, naps too short when she does take them, super long wake windows, crashing at night and then sometimes sleeping 13 hrs at night. She’s consistently only had one nap for the last 2 weeks but it is only a morning nap and she doesn’t seem to be able to make it if I push her to taking one nap at noon. She gets overtired. But then when she has a morning nap she refuses her second nap and then has an 8 hr wake window to be put down early

for bed at 6:30 to make up for her missed daytime sleep. Any advice? Will this pass or do I have to transition her to one nap or force her to stick to a napping schedule? Help!
