Hello all...WiFi Kit 8 with OLED


I have the WiFi 8 kit with the OLED on it. Working fine. Trying to play with the display, and found that
Heltec.display->flipScreenVertically() does not appear to work. mirrorDisplay and invertDisplay do work for me. Do you have to do something else to make this happen? I tried these commands on the factory test sketch in Arduino IDE, and put the command before any screen commands.
