Chrome extensions are updated in the background (every 5 hours, based on the code here).
Every few hours, the browser checks whether any installed extensions or apps have an update URL. For each one, it makes a request to that URL looking for an update manifest XML file.
Keeping things in sync is important.
It might be possible that your browser extensions are outdated, even though a new version of the Spirit extension is available. Once the desktop application or the runtime player is updated, this might lead to unexpected behaviour.
Features are added along the way and the data format might change over time.
chrome://extensions and tick the Developer mode checkbox at the top right, then press the Update Extensions Now button.
