I could not use the remote. Tried to pair via the app. Noting seemed to work. Even pressing the reset button on the back did not work.
In the B&O app I restarted the Countour. Then I tried to pair the remote with the Contour from the B&O app. This approach worked.
IMHO the Beoremote is so elegant, but cases like this happen too often. I am not sure that I'll buy that remote again, since it's more easy to control the TV via an app.
