I cannot check the information on the messages in the dashboard because you have set it to require pro plugin to see that information. That is to say, you provide a link to see message information, but when clicking on that link a popup shows that I have to purchase the pro version in order to see that information. This is a limitation on the plugin which violates WP Plugin rules.
Plugins are supposed to be fully functional, not limited and requiring upgrades to be able to use all of the features that are shown. This is clear in the plugin guidelines.
"...you cannot "cripple" functionality in the plugin and then ask for payment or provide a code to unlock the functionality. All code hosted by WordPress.org servers must be free and fully-functional. If you want to sell advanced features for a plugin (such as a "pro" version), then you must sell and serve that code from your own site, we will not host it on our servers."
Please fix these issues. If you do not want to allow admin to access messages from the backend or the information about them, then remove that functionality completely. You have made it very clear in the description that you have a pro version. You don't need to cripple the plugin functionality to force the upgrade.
