Multisite SEO Premium Not Working

The plugin works fine within each sub-domain, but if I need to redirect to a different sub-domain, it doesn’t work.

Examples:
https://dating.christiangays.com/forums/topic/upcoming-tech-talk/
-> https://christiangays.com/forums/topic/upcoming-tech-talk/

https://resources.christiangays.com/forum-descriptions/
-> https://christiangays.com/forum-descriptions/

https://resources.christiangays.com/bp-members/
-> https://dating.christiangays.com/bp-members/

https://resources.christiangays.com/product/marriage-holy-union-certificate-personalized/
-> https://store.christiangays.com/product/marriage-holy-union-certificate-personalized/

https://resources.christiangays.com/forum-descriptions/
-> https://christiangays.com/forum-descriptions/

https://christiangays.com/fraud-scammer-names/
-> https://dating.christiangays.com/fraud-scammer-names/

None of these work. I am using Regex which seems like the only reasonable option.

Would really appreciate help with this plugin. I have to keep asking my Systems Admin to fix these links in .htaccess which costs me money. It would be so much better if the plugin worked.
