Basic `wiring` identifiers are undefined?

[zfields]

As you can see in the screenshot, VSCode claims the most basic wiring APIs are not defined.

I have validated the paths in the c_cpp_preferences.json, and they are correct. I also noticed that the problem matcher claims it is checking against C/C++(20) in the PROBLEMS tab. However, the standard specified in c_cpp_preferences.json clearly states c++14.
For the record: The c_cpp_preferences.json file was generated by the extension. I did NOT modify the file; I only verified its contents.

The code compiles without warnings, and if I press F12, then it will find the definition of either of the API.

Hi @zfields! I'm was able to reproduce this issue, although eventually the identifiers did resolve. Given that F12 works, I suspect this is an issue with the C++ extension that powers our IntelliSense. I'm going to transfer this issue to the cpptools repo for further investigation.

Sorry, looks like I don't have permission to transfer. Can you open an issue with this template?
