I purchased this camera and have found that all of the menu tabs that are shown in the manual do not appear on mine eg: customization and the star. Also when I go to t=other tabs there are items missing. Please help I have been trying and asking these questions and haven't gotten an answer, thank you.
Your gueston has been sended long time ago, so you have maybe solved this problem sooner or later.
If not, this is the reason: your R6 is keeping A+ (automatic mode). Change exposure mode.
For example Tv, Av, M or P will give you all menu tabs.
