Flagged mail in mac mail is not functioning properly
I am having a lot of issues with my flagged email since I've upgrade to MacOS High Sierra.
Basically my flagged mail in mac mail is not functioning properly.
Emails in my Red flag folder remain in the red folder even when I change the flag colour to sort that message into another folder.
Flag counts on each folder are wrong.
Even when a flag is removed completely the mail stays in the folder.
I use flags as a todo list and this issue makes it impossible to work my system.
Is there a fix coming? Is anyone else experiencing this? Is there something I can do on my end to fix it.
Thanks
