Is there any update from Apple regarding this?
I have followed every single possible update/suggestion in this thread and others to retrieve the emails in my IMAP (AOL) account subfolders (which still exist when logged into AOL via web and via PC email client) on my iPhone (12 Mini) mail app to no avail.
I have removed and added the email account in question multiple times,
I have re-entered the password
I have adjusted every !@#$ server setting (including the IMAP Path Prefix),
I have deleted and re-installed the Mail app,
I have used the Add Mailbox function (which is stupidly hard to find)
I have Fetch set to 'Push - Automatically'
The subfolders that are available on my IMAP account do display when using Add Mailbox (so I know that the app is connecting), checking them off causes the folder name to display in the folders list, but no amount of fiddling retrieves any messages that are located in these subfolders.
I've spent hours of my life trying to fix something that should be basic and WORKED PERFECTLY FINE before. And I'm very very frustrated.
