Since the android update it will not stay connected to my headset, I've had to uninstall reinstall, no changes. I've lost all of my settings. And it is absolutely a useless app for me now. Edit: after cache clear, uninstall, and removing pairing info; finally got it to work. I had to redo settings, but at least the ANC is working again. The app randomly turns itself on in notifications trying to engage moments when the earbuds are docked in the case. Annoying, but at least it is working.
