Blind Spot Monitoring system - malfunction? - DS7 Crossback

Hello,

I own a DS 7 Crossback Diesel with 177 PS. I’ve noticed that the Blind Spot Monitoring system alerts me later than my previous Hyundai Ioniq Premium Hybrid did. Is there a way to adjust the sensitivity of the Blind Spot Monitoring system to provide earlier warnings?

Additionally, I’ve encountered an issue with the latest software update (version 42.03.33.42). It appears that the certificates for this update have expired, preventing installation. Are there any updates or solutions available regarding this issue?

Thank you for your assistance.
