We know 😉 , at the moment the new version of the extension is already on the Chrome store, however, since the plugin changed, Lansweeper must also be updated so it can actually use the plugin.
At the moment, if you try and install the new plugin, Lansweeper will still attempt to use the old plugin. Once we release a new version, the new extension should work (be sure to check the changelog as it should be mentioned: https://www.lansweeper.com/changelog.aspx ).
