Your Plugin with Elementor

I don’t have a fully finished page yet.
I’m wondering if you have experience with using your plugin and elementor?
Trying to upload media in the wordpress classic editor and then switching to elementor to continue design elements on the page is proving problematic.
I did have some success when I uploaded 7 test images using classic editor, but when I went back to that area the images were no longer visible but they were somehow still loading on the test page.

Suffice it to say I’m inexperienced and thoroughly confused.
Thank you.
