I can download the M app to my iPhone without any problems and then display the Cumulus code on the Apple Watch. After half a day, the M connection disappears and it says: 'Unfortunately, we have no connection' and I have to open the M app on my cell phone first so that I can read the Cumulus QR code in the store via the watch. This works perfectly with the Supercard and the code can always be called up on the watch if required. Can anyone help me? Z. Mangold
