## Including jquery files (or calling them remotely)
Your plugin has included your own copy of a core jQuery file (or called it remotely, probably from Google or jquery.com).
WordPress includes its own version of jquery and many other similar JS files, which have all been rigorously tested with WP and many of the most common plugins. In order to provide the best compatibility and experience for our users, we ask that you not package your own (especially not an older version) and instead use wp_enqueue_script() to pull in WordPress’s version.
Please review https://developer.wordpress.org/reference/functions/wp_enqueue_script/ and update your plugin accordingly. You need to both change your code to use our jquery as well as remove the unused files. Remember! Keeping unused files out of your plugins makes them smaller and less potentially vulnerable! if you have any jquery files included in your plugin that WP core has, just delete them.
Offloading jQuery js, css, and other scripts to Google (or jquery.com or anywhere else frankly) is similarly disallowed for the same reasons, but also because you’re introducing an unnecessary dependency on another site. If the file you’re trying to use isn’t a part of WordPress Core, then you should include it -locally- in your plugin, not remotely. Please check first. We have a LOT of JS files 🙂
If your code doesn’t work with the built-in versions of jQuery, it’s most likely a no conflict issue.
If you can’t guess, we -really- want you to use our JS files, and if you can’t, we need to know why so we can fix things for everyone. If you’re just including it because you want to support old versions of WP, or because you think they may not have jQuery, please don’t. If they don’t have the default jQuery, a lot more than your plugin will break. And if they’re on older versions of WordPress, they need to upgrade.
We do not recommend you support anything except the most recent version of WP and one release back. After all, we don’t.
You’re using https://developers.google.com/loader/#null to load jQuery from Google. Don’t do that.
Please make sure you’ve addressed ALL issues brought up in this email.

(While we have tried to make this review as exhaustive as possible we, like you, are humans and may have missed things. As such, we will re-review the ENTIRE plugin when you send it back to us. We appreciate your patience and understanding in this.)
