sorry for the typo, i had meant v1.65.2
i see that you started a topic about this same issue, and that i contributed to that same topic.
so i am not seeing a difference from your current topic and this old topic?
https://forum.rclone.org/t/empty-directories-remain/26228
i think that is correct. it may appear that rclone mount has deleted the dir but it will re-appear after --dir-cache-time expires.
rclone cannot delete an empty dir.
rclone cannot create an empty dir without --s3-directory-markers
