I believe its just a mere assumption, when you say "I know". What I know is the said features only work when low data is toggled off, but I didnt think that was the intended behaviour. Like I did mention, these are shortcuts. I believe they have to be functional everywhere, and when you say the functions to be called do not exist, I wonder if it is impossible to make a post or post a photo in basic mode from your end, because those functions work here.
