You need to modify the registry.

1. Open regedit

2. HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Policies -> System

3. On the right, you will see ConsentPromptBehaviorAdmin, ConsentPromptBehaviorUser … etc.

4. click on empty space, ADD DWORD(32bit), then name it “EnableLinkedConnections”. Double click it and set the data to 1.

5. Reboot and you will see the mapped drives showing.

This has worked for me.
