Hi, thank you for reviewing! 🙏
I’m not entirely sure if this is exactly what was requested in this issue. #737
If not, could you please provide a bit more guidance

Hi @donMichaelL - thank you for opening this PR! Unfortunately, I had to revert it because I noticed it edits the /build file. Can you please reopen a PR with changes made to files in /src? Thank you!

@donMichaelL no worries took care of it in this PR: #782 thanks for finding these

Thanks a lot! I suppose the issue was fixed. I’ll go through most (if not all) of the docs for a full review. If I spot any bugs, I’ll edit them directly in src/ and then merge into prod, right? I noticed the “Edit on GitHub” button is gone — this button pointed to the build/ directory — so I guess that’s no longer needed fix.
