I had to go to icloud.com and spend about an hour command+A ing my entire junk folder and putting it into my inbox.
When I tried to do the same in the Mail app, it just keeps going in circles, moving the files to my inbox then immediately back to my junk folder.
I don't know what in the world is going on, but it isn't appreciated. A first party mail client over a decade old shouldn't be having these ridiculous issues.
I am legitimately afraid to open my mail app now on my Mac and I am not sure how I am going to properly manage emails now... icloud.com/mail is frankly too limited in features to be able to properly sort my email the way I am use to, and frankly I do not trust AI enough to do the right job, it does a good job, but not perfect like my rules did before everything got messed up.
