If the user is going through initial setup because they
removed the plugin, but added it back
invalidated/unset the token
opened the vault on another computer, with a fresh copy of the plugin
etc
The trello view will show
No connected note
Token is required
Button to set up trello plugin
After adding the token, nothing changes
To get the card to display correctly, obsidian must be restarted or another note must be connected, etc. Anything to invalidate the cache or update the plugin state
To fix this, when a new token is set the cache should be invalidated and the current file reprocessed.
