Kettler alpha run supported?

Hi Thierry,
well I bought the Alpha Run 600 and I can’t get a conncetion with Zwift.
I use an iPad and the Bluetooth connection says I am connected with an “S8”, well that’s cause
the Alpha Run 600 is the “S8”. Only another name cause Trisport overtook the Kettler company.
But when I start Zwift I can’t get a connection with the Zwift App.
The iPad is connected and the Kettler Alpha Run also says it is connected, but at Zwift the Alpa Run 600 won’t appear, if searching the treadmill. Any suggests?
Should I try wiht PC?

Thank you and best regards
