Dear Ruz_San,
There are dozen of people complaining about this issue and all you can suggest is to clean the connectors? How about you provide some evidence that Microsoft did actually something about this April windows update? I had no issues with my surface pro 4 device until the windows update. To date after hours spent fixing the problem, I still can't use the type cover . Yet every engineer is suggesting to wipe clean the connectors. What a joke!!
