Lesson 4: Compiling Errors - Not recognising Adafruit IO library? Answered


I have successfully connected to Wifi on the previous lesson, but in trying Lesson 4, it seems there is an issue compiling the code, which I think is linked with the installation of Adafruit IO for Arduino library.

It has been installed (tried various versions of it), but doesn't show up as Orange text in the code, and the other libraries all turn Orange - Looks like an issue, but not sure if this is the issue!
Have attached the code and compiler error screenshots.
Any help would be much appreciated!
