I'm not being offensive, So please don't take it otherwise, But please try to understand my issue..... you are just working so hard to tell me how this plugin works, but what I'm trying to say is "This plugin worked for me perfectly to cross post a WP post couple of months ago, with all my standard settings and Editor Plugin, but now its not working"......you are just trying to find a way to somehow get it working for me, but you are not focusing on what I'm saying.....If I'm not clear, then just please let me know, I'll try to explain it in a more detailed way.
The workaround that you did this time has messed up the main page of the website.
Check it here ::: https://yatrahelpline.com/staging/home/
It should look like this ::: https://yatrahelpline.com/home/
I understand that the plugin won't work with the builder elements in a post, but it should work with a simple post, which I tested in the past and it worked perfectly (It worked with my Editor Plugin too, but without special builder elements).
Earlier I successfully used it on this post ::: https://yatrahelpline.com/staging/top5-spb/
And the result was simple and straight like this :::> https://yatrahelpline.com/staging/community/forum-test/top5-spb/
So from now on please try to focus on this post only and leave the other posts, this plugin won't work with them.
