Radio Button Not Showing

Same. No change to default button bindings for my Logitech G920. Was working initially. Disappeared from screen at start of My Team career mode during practice/qualifying for first race. Have checked bindings, unbound, rebound. It's disappeared entirely. Not just OSD visual prompt, but the radio messages menu fails to launch when the bound button is pressed. Very irritating not being able to communicate with pits.   

Also tested in single Grand Prix with the same result.

This also happened to me. I did a quick GP to warm up. I then had a cool idea for a my team car before continuing with driver career. So I did that then but didnt start australia. I quit to main menu to enter driver career to start Australia S2. It is not showing for whole weekend?

I am also facing the same issue on PC. The option for the radio button does not show up at all. I have tried rebinding the buttons and reloading the game but does not show up at all. It is almost like the feature has been removed all together
