In what way is it incomplete?
Optician Engage is NHS only so won’t be in the normal Oticon pages.
Second link I linked, shows it says only iPad, iPhone and iPod Touch.
Engage is Opn technology, not even the Opn S tech.
Also my friend has the Engage PP, a personal iPhone and work Android phone.
He can confirm that he’s never been able to connect his work phone despite it being an Android that works with the Oticon More.
