Unreal Engine: CommonUI - In Game Input Not Working

I stumbed upon an issue in one of my side projects where game input was not properly registering, especially the actions that are also used by UI interactions for example left mouse button.

The cause seemed to be that I didn't had setup CommonInputActionDomainTableAsset, once i created it (It's DataAsset) and set it up in Common Input Settings - then restarted Unreal Editor the input is working back again.

Few days of going through depths of the Unreal input and it's solved! :D
