Why is the MyButton no longer activating a radio station?

Due to the change to Bang & Olufsen Radio, MyButtons set up to activate TuneIn stations will no longer work.

To store a Bang & Olufsen Radio station on the MyButton instead, please follow these steps:

In the Bang & Olufsen app, find the station you wish to store on the MyButton and start playing.
On your Beoremote One or Beoremote Halo, press and hold on the MyButton where you wish to store the radio station. The speaker will confirm with audible feedback that a MyButton is saved.
Press the MyButton to activate the stored radio station.
