Give it time.
I haven’t decided if I love it yet.  If your shoulders are rolled forward even just a little bit the straps cut into your arms,  Ive had this product for a few weeks and the straps don’t cut into my arms as they did when I first tried it.  Takes some getting used to. It’s best to start with a shorter amount of time and progressively wearing it longer as your body adjusts to a better posture.
