I took another Win10 laptop which never had MP or any ublox stuff installed before. Win10 automatically installed a ublox vcp driver 2.24.0 when i plugged in the m8p. With that driver, Mission Planner SurveyIn works perfectly well - all good.
However I am not able to get MP and the m8p working anymore on my first laptop. Even when I uninstall everything and all ublox drivers, Win10 automatically installs the location sensor driver once I plug in the m8p, and MP subsequentially breaks.
This issues began when I updated u-center to the latest 8.24 release and the installer automatically also updated the ublox drivers.
So there is definitely an issue with Mission Planner which is not compatible with the new ublox drivers.
@Michael_Oborne it would be great if you could take a look at this.
