Just purchased a Wio Terminal… Immediately ran into issues not seeing anything on the LCD, but found that using Arduino portable for my Wio worked to avoid library conflicts with the LCD library, so all works there.
I wanted to try this WiFi example, but now getting this error…

Error compiling for board Seeeduino Wio Terminal.
I don’t know what this error refers too, I believe I have all the needed libraries installed 
FYI, I have updated the RTL8720 firmware to 2.1.3
