Same.. nothing I try to change up the routine seems to make a difference. Once they drop to one nap in a few months I find they’re knackered by bedtime so hopefully might sleep better then. Think my first was on one nap around 14/15 months.
Have you tried doing your longest nap on a morning?? Our LG has a 1-1.5 hrs nap on morning around 10.30 and then a 30-45 min nap on afternoon around 2pm. I find if she had a long nap on the afternoon her sleeps worse she takes longer to settle on an evening, used to wake through the night etc.. you could try a shorter nap on the afternoon and see if it makes any difference?

It's still normal for sleep to be inconsistent. Illness,teething, growth spurts, etc can all impact.x
