In general you plugin will auto update with the latest code and bug fixes automatically. It is not immediate updates however. To keep the site speed up the source code is cached and the widget code will only load the source from our host via API every 2 days. So you will get any fixes automatically, but only when your 2 day caching expires. You can force the widgets to recache by adding the following (?liveDevmode=1) to the end of your DirectoryImport plugin URL https://ww2.managemydirectory.com/admin/go.php?widget=google-yelp-data-plugin
It just needs to be done once. Shortly we will also have a refresh button in the Configs section.
