Oops guys
It doesn't work
I should have been thorough - before posting
When Phone is connected to USB Type-C - fine
When PC is connected to USB Device - fine
But when Phone is connected to USB Type-C which is in turn connected to PC - Not working
What you plug in second does not connect
When unplug Phone from USB Type-C - the Pen-Drive shows
When unplug USB Type-C from PC - only then does the External Storage mount and show, on the Phone
Sorry
@thetrueman for getting your hopes up
Is there any way around this
@Erel
Sorry again
