Thank you for your post.
Just to clarify are the points not showing on Google Earth anymore?
Depending on what you are doing with the file in that environment, it’s possible that visibility for features has been disabled, etc.
Unfortunately, this would be a Google Earth-specific issue and not specifically linked with the Avenza Maps export. However, if you are able to share the file that you are using with us via support.avenzamaps.com and be sure to outline what you are doing that is causing the features to disappear, we’d be happy to take a quick look and see if we can’t figure out a solution for you!
If you are experiencing a different issue that I am not fully understanding, please let us know when you reach out to us via the support centre!
