+You might need to change [the Gmail IMAP settings](https://mail.google.com/mail/u/0/#settings/fwdandpop) on a desktop browser to make it work:
 
 * When I mark a message in IMAP as deleted: Auto-Expunge off - Wait for the client to update the server.
 * When a message is marked as deleted and expunged from the last visible IMAP folder: Immediately delete the message forever
 
 Note that archived messages can be deleted only by moving them to the trash folder first.
 
+Some background: Gmail seems to have an additional message view for IMAP, which can be different from the main message view.
