macOS 13.2 mail attachment at the end is not possible automatically
Since updating to macOS 13.2 yesterday, attachments can not automatically be placed at the end of an email after writing the mail text (although "attachments always inserting at the end of the mail" in the mail edit menu is activated). Rather, the attachments are placed directly below the mail text and above any signature or above any text of an email it is responded to.
This is a new bug in macOS 13.2, which was not present in macOS 13.1.
