Gmail draft emails not being automatically deleted after being sent
I have the same problem as asked in: https://support.mozilla.org/en-US/questions/1440873#question-reply (I can no longer reply to that thread as it has been archived, so I am asking again now in search of an answer).
To reiterate the problem, draft emails are save correctly into the 'Drafts' folder in both Thunderbird and the Gmail web app, but only Thunderbird will correctly delete the draft once the email has been sent. In the Gmail web app, the draft email remains in the 'Drafts' folder.
Why can't Gmail automatically delete draft emails that have been sent? Is there a solution?
I am using Thunderbird 128.5.1esr (64-bit) on Windows 11.
