I added an edit to my original post above relating to the settings required when using the Arduino IDE to load code onto the V4 board but the comment relating to the change required to the ~/Documents/Arduino/hardware/heltec/esp32/boards.txt file may not be as clear as it could be. The entries that need to be updated in the boards.txt file are as follows:
heltec_wifi_lora_32_V4.menu.CDCOnBoot.default=Enabled
heltec_wifi_lora_32_V4.menu.CDCOnBoot.default.build.cdc_on_boot=1
Clearly no end-user testing is occurring before leaving the development office, such a mess. 
Add to Arduino IDE Board Manager This gives the option to add 3.0.3 Version of the Github library using the board manager. .Note the3.0.3. Copy the link address and pasted into Preferences --Additional Board Managers URLs.
I had already followed the UniquePete directions already; Heltec LoRa32 (v4) did not show up in the board list. Might have done something wrong.
Time permitting; I may redo with only using the library json link in Preferences.
