The Feedback Hub is absolutely just for feedback of problems up to Microsoft. It's not a troubleshooting or help forum. It's just a way to get problem reports "officially" to them:
Of course, they almost never act on anything reported there. Just look at the issues people are reporting on the Taskbar (filter Category to Desktop Environment and then Subcategory to Taskbar). The top Trending problem is about their having removed the ability to "never combine" taskbar icons. It's been there for over a year with almost 17,000 upvotes and 1886 comments. Yet, not only have they never fixed the issue, they've never officially responded to it.
