I am using addon version 3.1.0 in Thunderbird 115.6.0.
To report a spam mail, there are two options: Use right click on the mail, then Report It; or use the Report It button in the mail. Both work on mails in an IMAP folders. But in a local folder, only the first option works; the button in the mail seems to do nothing - at least it does not open a mail window to report the spam mail. If I choose the setting "Delete" as standard action after reporting, the mail is in fact deleted. So something happens when pressing the button, but the reporting mail is not created.
