Hello,
Sorry to hear you are having issues. The multi-column/row taskbar tray icons for Windows 11 have been requested by others, and I believe Support and Dev team know about it. Hopefully, something come up in the future version.
As for the narrow vertical taskbar, do know that, you can set the taskbar to be resizable. Once that is set, you can simple click and drag the taskbar wider.
