I have found that the L2 R2 buttons no longer work. They were previously assigned to the toggle switches.
I have tested the rim on a PC so I know it's not a problem with the rim.
All devices are using the latest f/w versions.
It's making F1 a pain to play as these buttons are needed to navigate sub menus, and I was using them as an ers short cut on track in F1 2018.
