I have a component selected in prototype mode, but there is no "Fix position when scrolling", moreover I am sure there used to be one. the selected component is selected for sure, it's blue, and on other artboards it used to work perfectly. I really am beginning to get frustrated, could someone please help?
This comment alone just solved it for me after an hour of searching because it has changed so often. Anything within a group does not have the option of 'fix position when scrolling'. Confusingly, it doesn't even show the possibility if you select something from within a group. Seriously, for a program that is helping us design good user experiences, this is a horrible user experience.
Tips for the dev team:
Leave the 'scrolling' section where it is in the prototype sidebar, but make it light grey (inactive) if it can't currently be used! Like all of your other interactions, it shows you can do it but only when you complete the steps prior! The fact that it isn't there at all gives the user no indication anywhere that it is something you can actually do.
While it is greyed out (inactive) can you put a little info hover so that it tells people that items within a group cannot be fixed? That way we know how to fix it.
Thankyou devs, I know your job is hard but this one is a bit of a UX fail
