Hi,
You can set up the custom app for Facebook in the plugin so that the blocked URL is altogether avoided. To set up the custom app, go to the miniOrange plugin -> custom app tab -> select Facebook from the drop-down and follow the instructions given below.

Please email us at info@miniorange.com if you face any issue during the setup.
Thanks
