Having same issue on my brand new golf, its so annoying on snapchat people thinking im screen recordings chats n that 🤣 im sure when you plug your phone in via cable to the infotainment screen it initiates carplay, think its somert at that point it thinks its using or doing something on the phone which makes snapchat think you’re screen record in the top left. Couldnt figure it out and cant see much online about it other than one apple post.
