Currently buttons to change transport mode (BUS, TRAM etc.) are interpreted by screen readers as two separate buttons: the label and the switch/button. Also other buttons in the settings menu like "avoid transfers" and "wheelchair" don't work when clicking the label.
The label for buttons should be marked as a label and connected to the button to make only one tabbable element with a visible focus style. Clicking the label should also activate the button. Also screen reader users need to be aware if the button is active or not.
