How to Fix 'SOS Inoperative' Message on Mercedes C-Klasse?

Hello everyone, I own a Mercedes C-Klasse and I'm experiencing a general electrical malfunction. Specifically, I'm getting an 'SOS Inoperative' message on my dashboard. Interestingly, I've tested the SOS system and confirmed that calls can still be made, so the system itself seems to be functioning. My question is: Can the Carly app help in removing this 'SOS Inoperative' message? Any advice or similar experiences would be greatly appreciated. Kind regards, Chris.
