App freezes / disconnects from processors

Recent app update is causing new problems after years of satisfying usage. Opening the app shows a notification that both processors are disconnected which then clears in a few moments. Yes, both processors are connected. Then the app is frozen. I am not able to control audio sources which is critical for me to be able to work (many Teams meetings!). App does not respond to any other areas except to check the battery status and access the menu. Please fix asap!

Beep is too loud

When YouTube video is slow loading. Cochlear keep beep beep on and off Bluetooth that is annoying me most . I wish it keep lower soft beep.

Requires uninstall first

On my iPhone17 this update requires first an uninstall of the app to release app settings. Installing over the top was never going to work and that resulted in a lot of frustration. My situation is Cochlear N7 + ReSound.

Nucleus Smart app itself is fantastic and only wish it had presets. For instance, my settings for mini mic in noisy environments is perfect but changing settings back and forth to only the HA is wildly different.

Disconnects my implants every time now

Nucleus smart app worked just fine for almost 6 years! After the update, it’s looking like there’s a big issue with it. Now my implants won’t stay connected. It disconnects and forgets my devices immediately after I close the app. Please fix!!

Iphone connection

I can’t connect this app with my new iphone 17. It would recognize my processor, but not my resound hearing aid. Phone calls, microphone and TV could only be received with my cochlear . I’ve seen two cochlear audiologists and neither were able to help.
