Question about Philips TAB8505/10

I have been trying to connect to the device via wifi for a while now. I have tried with several devices (Samsung Galaxy S10, S20, A42, Z Flip 3 and a MacBook pro M1). Unfortunately, I can't connect despite resetting several times. I always get the message "No IP address could be found". Does anyone have any idea why this is happening and how I can get the connection working? I would like to integrate the soundbar into my smart home, but I can only configure it via the app.
