Hi Robin,
thanks for getting back to me and verifying that everything works now.
Not sure, there might be an issue with some of the older version when the plugin was installed and now resetting the values with the new version solved the problem.
Anyways, I will keep my eyes on this and run more tests to be sure that the feature works properly.
Also, we are working on a new function for the next version where users would be able to trigger the Check process with a button click. This should improve accuracy.
