Why Glow doesn't adjust fertile window?

Hey,

does anybody know why Glow doesn't automatically adjust the green fertile window to measurements of body basal temperature (BBT)? My temp. rise isn't on the day glow says it is ovulation day..

Is it possible to adjust it manually? 😊

What experience do you have with this simpto-thermal birth control method? 😊

Thank you for answers 🤗
