There was an error during import.
Unexpected exception from plug-in (Execute): Adxstudio.Xrm.Plugins.Products.ProductReviewsAggregationPlugin: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Faced this error during ADX retail portal deployment on on-premise CRM instance. This is a known issue in CRM 2016 that is related to installing everything on one box. The update rollup that is in preview will fix this, otherwise you can try to change your required assembly mode from sandbox to none.You can also see what isolation mode of a plugin if you open the Plugin Registration Tool.

1. open the Plugin Registration tool
2. connect to CRM instance
3. Right click on an Assembly and choose update
4. Now see the Isolation mode
