I have tried both the standard and the beta and my start icon and task bar are not centered like I wanted. After each time I clear the folder in the programs files (86). I am beyond frustrated. It worked when I first downloaded it for 3 weeks or so and now not anymore.
If you are using Windows 11 then if you enable the enhanced taskbar feature in Start11 taskbar settings then you cannot centre the start button. It does explain this when you enable the feature in the beta however.
Disable that and you should be able to reset back to centre mode.
