Series 7

Sucks when Apple series 15 pro max connects better with both cochlear processors than this app update

Disappointing Update

My Nucleus 8 processors are visible in my iPhone's Accessibility settings, including their battery levels.
The new Nucleus Smart app at times detects one or both processors, but the pairing handshake fails repeatedly. The app in the past was excellent but this version seems not to be compatible with latest IOS.

Latest update

…..is not a step forward / keeps not recognising devices when opening

Processor Not detected

This app is making me angry. It constantly tells me it can’t detect my processor and therefore I can’t use any of the functions. Got it to work once by unpairing and then re-pairing but I should not have to do that in order to adjust the volume, etc. Please fix this.

Drops devices

Forced to update out of the blue less than a month ago. Unpair then repair. No issues till last night. I used the app for hours during the day, then I went to adjust my settings at a concert and “poof” no devices. I’m done with this app until there is consistent connectivity, which to me means it never drops once connected. I did not have this issue on the previous version of SmartApp.
