New mail in IMAP folders other than INBOX does not sync


I use server-side filtering to move mails from my INBOX folder into various sub-folders of INBOX. When a new mail is received into one of the subfolders, it does not show up in MailSpring.


This is an IMAP account with all new mail arriving into either the INBOX folder, or a specific subfolder of INBOX.

Try this issue is infuriating. These people simply don’t care. How can they not have folders sync. This software is not functional.
