Only once I've got any response to Feedback. After getting it I never opened another case again.
Can't recall what exactly was the issue but after macOS update, some bundled software stopped being so friendly and required more actions to achieve a goal. Some built-in functionality stopped being more useful than 3rd party products.
I've opened a case to try to tell Apple in what way their update has broken my productivity, pointed out what was needed to get results before the update and how more labor user had to do after the update.
Got the most Apple answer possible: "this works as intended".
Just another example of Cook's hostility towards users to make Apple more attractive to investors.
