I have a problem in connecting wemos D1 Mini V2.2.0 to Blynk Trying to Load Sketch through Aduino IDE 1.8.7 Ver

Your problem was the inverted commas. Sometimes when you copy a sketch from a website they take the wrong format and this is highlighted by the stray ‘\223’ and ‘\224’ compiler errors.

Not sure what you mean by professional use but I would say always buy the latest version directly from WeMos.
