Nord Stage 4/Piano 5 with WIDI Master & M4 iPad iPadOS 18

[Amplified]

Newbie here.

I was testing out the WIDI Master and it worked with the Pianoteq 8 app on my M4 iPad OS17. When I play the keys, it mirrors on the app and displays the chords.

Ever since I upgraded to OS 18, nothing seems to work. The blue light on the WIDI is solid and shows connected. But app does not work. I tried MIDIculous and same thing.

My NS4 is stock settings.

Anyone facing the same issue?
