[ISSUE] WorkBench Intellisense "No Storage Class"

[ScruffR]

Could it be that your build is targeting the Core?
Try to explicitly change the target platform.

This may be a related issue where the platform setting was not correctly applied at build time

[ISSUE] WorkBench compile APP_FLASH overflow

Oh I see - your local gcc-arm build is incorrectly targeting Core, which is why the code doesn’t fit. Your cloud build was targeting Photon. Try doing particle set target device again.
