Impossible use UE4 for a coop or mp listen server game due the unfixed network errors since 4 years

Are there any updates on this? It would be really great to have proper client interpolation from the view of the server. It’s causing greatly higher bandwidth on my game to use the workarounds like p.NetEnableMoveCombining but things work perfectly when clients are viewing other clients or the server, it’s only the server’s view that is affected. Using these bandwidth heavy workarounds are extra wasteful here since it’s only to fix the viewpoint of one player (the server), yet everyone pays a much higher bandwidth cost.
