We conducted testing and verification, and the code can be uploaded and run normally. The APP can successfully control the LED switch.

The code you provided has issues. We suggest copying and pasting the code from the tutorial link and then uploading it to see how it works:

If there are any errors during upload and execution, please provide us with a screenshot of the error message so we can help you analyze and resolve the issue.

It’s ok now after I re-download the sketch from the tutorial page. Both in Arduino Cloud and in Arduino IDE.
Thanks!

sincerely yours,
Joseph Cheng
