Hello,

Flex Container has been in the status of the development and Alfa state for a long time. Elementor developers have changed the status to Release Candidate and changed the structure of the container element and styles. As the result, some of the features related to the container, including the “Stretch container” do not work.

We will fix this and improve the compatibility of the container in our future update. Meanwhile, we recommend not to use this element.

If you have any questions please feel free to contact us.

Best Regards
