ATC keeps telling me to please expedite my climb to my assigned altitude

Ok, seems a liitle bit strange isn’t it? For most people bug seems to be fixed meanwhile as it is said in this topic:

So is it or is it not? And if it is fixed, what could we do to get it also running. As I do not use vatsim and want to fly with real weather, it is unplayable for me more or less? I am thinking about reinstalling the whole MSFS, maybe this would help? Anyone any idea?
thanks for your answers, good to know that I am not the only one with still this problem.
