Why is my Phonak hearing aid no longer switching on automatically after being removed from the charger?

The hearing aid does not switch on automatically after being removed from the charger. I have to use the button on the hearing aid to turn it on.

“Auto On” feature is disabled. To activate “Auto On”, please follow the steps:

Open myPhonak app
Tap on “Devices”
Tap on “Auto on”
Enable “Auto On” by moving the slider from left to right.

If the problem persists, please follow the steps above to enable “Auto On”, then immediately close the myPhonak app and remove it from the background. To remove the app from the background swipe up from the bottom of your screen and then swipe the myPhonak app card up until it disappears. Once this is complete do not navigate back to the “Auto On” setting. You can test that Auto On is still enabled by placing the hearing aids in the charger briefly, then removing them and observing if they automatically turn on.
