PlatformIO won't pick up code change

I have been working with Tasmota, and got it setup a while ago with PlatformIO. I was able to download the source and edit user_config_override.h and have the changes deploy to my ESP32.

Well I picked it back up tonight after a few months, and now when I make changes to the file and do a build, the changes are not honored.

Additionally, I downloaded a fresh copy of the repo and opened it and built it, and even it uses my old settings. It seems like there is an old bin hanging around somewhere that is somehow still getting deployed. I have VS code on a mac.

Please let me know where I should look.

Do you have multiple projects open in your current VS-Code Workspace?
Make sure you have selected the correct project / environment in the project environment switcher:

Yeah, I only have one project open in the workspace. I selected the project environment just to be sure, although I did not have to do that in the past, and I get the same problems.

I have exactly the same problem, for some reason my code changes are suddenly not recognized by platformIO any more, neither in the code itself, nor in e.g. platformio.ini.

Did you ever find a solution?

Is this also a Tasmota project?
Does this also happen with a brand new (non-Tasmota related) project?
