Hi @wpfleek thanks for the quick response the
.wp-embed-responsive .wp-block-embed .wp-block-embed__wrapper:before {position: relative;} relative;
placed in the CSS did work. The videos are now showing.
As @manuxx34 and @rubidze mention we are using the Gutenberg editor for simple posts as the block format is much quicker for a lot of posts rather than using Elementor.
Is this something that will be updated in future updates because it has only happened recently with updates to the theme and wordpress updates?
