Unlikeable FMC?

I’m m currently writing my series and my FMC is highly insufferable for the first few chapters. She’s just clueless, spoiled, and kind of whiny.

Princess with a silver spoon and what not.

Her development comes and expands a ton over the book/s. Would that turn you guys off as a reader? My intention is to have her be unliked at first. She’s naive but not unkind.

I wanted something a little different than I’m used to and she was born. A bratty, fun loving, naive princess who, naturally, faces her world going to sh** and gets knocked down quite a few pegs
