Spam trash button does not delete the Spam in the Folder
The below information link from Gregory May doesn't fix the Spam trash button not working. Amazing! This was posted back in 2018 and the button still doesn't work. It seems like a waste of time posting messages on this forum. Clicking the Spam trash button on Yahoo desktop mail doesn't work with any browser you try it in. Yahoo stop giving your users the run around and fix the issue!
