Constantly drops connection making hearing aids virtually useless. A very expensive hearing aid that can't provide any funtionality over a cheap aid. All this because the app doesn't work after an android security update late 2021. ReSound will ask you to email them information then give lip service. Will be working with my audiologist to find a manufacturer that stands behind their product and recover the $thousands I spent on ReSound aids that are useless because of the app. UPDATE IT!
