Why would I have to do a cloud script just to update item custom data when I integrate the whole sdk into unreal engine? The only node that supposed to do that is Update User Inventory Item Custom Data and apparently it requires a server authentication which isn't explain in the documentation either.
That node doesn't do anything, I either get an error saying only the type title can access this function, if I use the title ID instead of player custom ID it says unauthorized and all type of garbage.
My question is, how can I simply, by using unreal engine blueprint with Playfab SDK retrieve and update Inventory Item custom data???
