Hi Mike,
While the version of Compass that you have is the current stable version, it seems that you're using the community edition of MongoDB Compass which doesn't include the Schema Analysis feature.
Please note that there are two editions of MongoDB Compass v1.11.1, MongoDB Compass and MongoDB Compass Community. Both editions can be downloaded from MongoDB Download Center.
MongoDB Compass Community is a free tool for developing with MongoDB and includes a subset of the features of Compass.
MongoDB Compass is available as part of the MongoDB Professional, Enterprise Advanced and Atlas Professional subscriptions (or evaluation period). If your company/organisation already has a commercial subscription and you have further questions about the MongoDB Compass usage, you should open a case in MongoDB Commercial Support Portal.
The Schema Analysis feature is not available in the MongoDB Compass Community edition. For more information on features comparison between the two editions see MongoDB Compass and Compass Community Editions.
Thanks and Regards,
Gaurav
