These are the 3 errors. I haven't messed with any of the code other than what was required.
I've double checked and it is installed and included in the script. In the Arduino IDE, it compiles and I get the errors through the serial monitor. In Vscode, it errors out before it's compiled. Could this be a version issue? I'm using the latest version of the WiFiManager library. I'll keep digging in the mean time. Still have yet to find the callouts for the mentioned methods. Thank you.
