Hello,
First of all, thank you for your purchase.
Regarding the yellow diamond in the plugin, please check the following article: https://coderevolution.ro/knowledge-base/faq/i-get-a-yellow-rombus-when-manually-running-my-post-importing-rule/
If the above is not helping solve the issue you encountered, can you send me, please, temporary admin login credentials to your WordPress install, so I can check this issue out? Send it, please, to my email address: kisded@yahoo.com.
Regarding the Google Scholar API, I checked it and it would fit much better in a new plugin (Newsomatic has different scope). So, I think this would need the development of a new plugin. For details about this, please contact me at my email kisded@yahoo.com
