Mime type mapping for HTML file for SFTP upload to an Azure Storage Account

[cs981khx]

I've purchased FileZilla Pro 3.62.0 which claims to have mime type mapping
https://filezillapro.com/docs/v3/advanc ... e-mapping/

The target is an SFTP location hosted by an Azure Storage Account = StorageV2 (general purpose v2) with SFTP functionality enabled
I can see that mime type for HTML file is already configured in screenshot attached, however after uploading an HTML file to destination, its file type is being set to "application/octet-stream"

Anyone else come across this problem or can help would be greatly appreciated
