Hi there, after very intensive research, our team has finally concluded that the issue isn’t due to our plugin, but is on Yoast SEO plugin side. In fact, there’s not a single issue but a lot of conflicts in their accompanying JavaScript files/code.
There are also different variations/combinations of these. For example, if you first try to edit the snippet title then you can edit the description also (although it keeps throwing JS errors). However, if you try to edit the description first, it fails to initialise the editor and collapses at once.
So we believe if you take references to all those JS errors in your browser’s JS console and contact with their support, you can find some good solution or at-least they can suggest something.
Additionally, we have tried with noConflict() modes, since we use jQuery for our plugin, that’s a pretty much straight-forward thing to taking jQuery out of the global scope into a separate object and working on that. But that also didn’t help – believing that’s not the issue.
We will keep this thread open for further communication, in case you want to provide more feedback from Yoast guys.
Thanks and all the best.
