The main one seems to be LinkedIn for some reasonDo you have to link all 4 listed social media links to be active? I have linked one but have no access to viewing any projects at all? I don't mind adding a second but I have no interest in having an instagram/twitter account! (I do get why they ask for it for validation; Just seems excessive for all of them).
don't worry about not seeing any projects on there. I don't either at the moment, maybe later today that won't be the case
