Hi Rob Knobben,
When you upload files via FTP for Azure App Service, they are placed in/Home/Site/WWWWROT directory. However, these files cannot automatically sink the document route (/VAR/WWW/WordPress/) of NGINX Server. This may be behaved because the FTP sinsiting method does not support build automation, including file synchronization processes that can be triggered by SSH verbs. To ensure that your web app moves correctly, you can consider using alternative signs that support build automation, such as GIT-based deployment or zip sins, which can handle file synchronization more effectively.
