Campagnolo EPS V3 bluetooth issue

[Rigo2020]

I have upgraded my wife's road bike for a second hand, but just like new bike, and it came with Campagnolo EPS Super Record 11 speed. I have used Shimano my whole life on a bike, so Campagnolo is a new thing for me.

The shifters and derailleurs work fine. The issue I have is pairing the V3 unit with MyCampy app (installed on my iphone Xs).

When the "mode" button is pressed (on the shifters) I can see a green light blinking on the V3 unit, but the app does not see any bluetooth signal. Even when I go directly to the bluetooth on my phone, I'm able to see a few signals from other gadgets, but none from the V3 unit.

Have anyone experience this issue?

How do I reset the unit?

Am I missing a step or something?

Is that possible the unit is faulty when it comes to transmitting bluetooth signal?

Any help is welcome!!!

Thanks
