EOS R6 II won’t switch to Manual mode

[MHolmes]

My R6 Mark II won't switch to Manual Mode internally, even though the dial is set to M (the screen says P mode). Has anyone ever had this problem? These other modes work fine (P, FV, C1P, B, A+ & A (Hybrid Auto). I've barely had this camera for a month.

This sounds like a camera mode dial fault - it probably needs to be looked at by Canon service.
