I need to find someone that can evaluate and resolve the black border around the published Google Slide represented on this page at [login to view URL]
I have updated the page to reflect what we know so far.
This is a Wordpress Site using the Divi theme.
If you think you can solve this problem, then select "Log-In" from the menu and choose the Google option. Once you have done this, I will bump you to admin and you will be able to immediately make your changes for me to review.
I have read the description and I can remove that border as per your requirements. I can do it asap. I have found that issue why that border is coming.
