Win10 pc quit connecting to the S9, which beeps to acknowledge charging when connecting to the USB port, but the pc does nothing.  Same cable and pc port still work fine for file xfers with my old S8 and did work at one time on the S9.  Developer options doesn't show "MTP" in list of USB defaults.  Is there a diagnostic app ?

I can see how this issue would problematic. I recommend using the smart switch make sure all the updates and drivers are downloaded to both devices. (https://www.samsung.com/us/apps/smart-switch/)
