Ok I just want to get some staff views on this problem, Rama posted it on answerhub and there has been not even a response.
In one sentence its this : RHIGetAvailableResolutions works in a Packaged Game in c++ but not when used in a BP node via plugin. The BP Plugin version works in Editor builds.
I am sure the problem is more complicated than flicking a bool, so I think it deserves attention, also Rama is one of the strongest community members and we need to respect his work.
I am by no means blaming anyone , I just want to see this problem resolved
