We are aware of this notice, but please note that it is not an error and does not impact functionality. Since the script loads in the footer, it doesn’t cause any delay in rendering the design.
We will try to address this in future updates, but currently, if you add the async, it may cause the script to load before the Geolocation code, resulting in a JavaScript error. We recommend using caching plugins instead of async, for example, LiteSpeed Cache. If you enable JS deferring there, you’ll get better performance and the scripts will load quietly in the background.
