IDK, but iOS mail is better able to predict where I want to move a message than MacOS, and it's been this way for a long time. I'm not talking about auto sorting, but manual sorting. In particular, MacOS does fine on my IMAP account with predicting in the 'move message to' box which folder I am going to want to put something into. However, iOS can do this with all different types of accounts, including Google accounts. On iPhone, I can click the forward icon, scroll down to move to, and it nearly always knows exactly where I want to move a message. Whereas, MacOS can only do this on one account. Thoughts? I searched for prior discussion on the topic, but maybe I used the wrong search terms.
