galaxys3 As I stated above, bugs are likely prioritised based on a number of factors. I use DND every night and have not faced any bugs while using it, so it isn’t affecting all users. If you’ve reported it via the official channels then that’s all you can do unfortunately.
As for changing your thread title, we change these for optimising search results so that other users may find your thread if they’re searching for the same issue. The second part of your title was redundant to the topic you’re discussing and would not help somebody searching for support. It’s clearly communicated in the Community Guidelines you agreed to when joining that we have the right to edit discussions.
