To see the updated status of the application, you need to refresh the page.
You need to refresh the page to see changes, e.g. editing a post, comment, adding/removing users to lists. When adding or removing yourself from the Community, the My Community list is updated only after refreshing.
To resolve all of this, we need an ability to update content optimistically then recover to real status of updated content (vote, comment, post, etc)
