[BUG] No "codecov/project" check is run although configured

[polter-rnd]

Describe the bug

I have the following .codecov.yml which seems to be properly configured to enable both project and patch checks. But neither in master branch nor pull requests I don't see codecov/project checks run.

Could you please tell if it's a bug or misconfiguration? Thanks a lot.

Environment (please complete the following information):

• Repo: slimlog
• Example PR: Some test commit for checking coverage polter-rnd/slimlog#10

I have a matrix strategy set up with different OS and compilers.

For distinguishing between different configuration I use flags. That's how Codecov job is set up for each runner:

    - name: Upload coverage reports to Codecov (Linux, MacOS)
      if: runner.os != 'Windows'
      uses: codecov/codecov-action@v5
      with:
        token: ${{ secrets.CODECOV_TOKEN }}
        flags: ${{ matrix.os }}-${{ matrix.c_compiler }}-${{ matrix.format_lib }}
        directory: ${{ steps.strings.outputs.build-output-dir }}/coverage
        fail_ci_if_error: true

And finally I manually trigger notifications because those jobs are run in parallel and for some flags there's no coverage (e.g. Windows):

    - name: Trigger notifications for Codecov
      if: ${{ !cancelled() }}
      uses: codecov/codecov-action@v5
      with:
        token: ${{ secrets.CODECOV_TOKEN }}
        run_command: send-notifications
        fail_ci_if_error: true

Here's a link to a full workflow file.

Expected behavior

Both codecov/project and codecov/patch checks are run.

Additional Information

I've already reset the repo and reinstalled the Codecov app, but it didn't help
