Good app serves its purpose but... – Notch Remover Review

For some odd reason, after a few days the image I place below the notch to leave a black bar at the top to make the notch unnoticeable begins to drift back up into the notch a little bit. I can re-do the image but a few days later it starts happening again. Not sure why?
