Sonos installing device does not work

I’ve installed the Sonos App. I’m trying to add a Sonos device. Once I’ve entered my e-mail en password, the App responds that I must allow Homey to control my Sonos. Then a homey screen appears telling I can now close the window. I push the ‘X’ in the left hand upper corners and then a screen with a turning arrow appears stating ‘Log in op de website van de fabrikant’. From there nothing happens anymore.
