While downloading email, pressing the detailed progress window button (small ^ button in the title bar) used to show a popup that contained progress on how download was going. Pressing that button nowadays does nothing other than turn it to a downwards facing arrow
Same for me

I am still affected by the bug with kmail-5.21.3. I think the progress popup is there but it is just not visible. If I enable "message preview pane below the message list" in Settings -> Configure KMail -> Appearance -> Layout and push the "Show Message Structure" button available via Settings -> Configure Toolbars, I can see a thin stripe of the progress popup in the border of the Message Structure pane. Then if change height of the Message Structure pane, I can see other parts of the hidden progress popup.

I have rebuilt kmail-5.21.3 with the fix mentioned in comment #4 and the progress popup now works again. Thanks!
