Latest version breaks video on page when Show video markup enabled

Sorry that you are facing this issue with our plugin.

Our plugin does not modify video embed code in any manner, it just parses the page content to grab video urls.

We are happy to help if you can provide the website url.

Looks like a compatibility issue with the Enfold theme and Avia Builder introduced in version 1.17.0. In version 1.16.2 there is no issue with Enfold. I can also confirm there is no issue with a default theme on latest version. This is a test site here with only your plugin and Enfold installed:
https://hcassociates.org/wp/home-test/

There should be a video there, but it does not show with Show video markup enabled and the code for it is completely removed and not showing in source. It shows with the setting disabled or the plugin deactivated. I am leaving the setting disabled on client’s site for now since we don’t typically support third-party themes.

Could you please change the settings so that video is shown on https://hcassociates.org/wp/home-test/ so I can replicate the issue on our end.

Setting is changed and you should be able to see the video now.

I tried to replicate the iframe issue on a test site but both iframe and regular WP embed is working fine https://schemaapp.myto.xyz/iframe-test/.

You can check the source code to verify schema makrup added by our plugin.

You won’t be able to replicate unless you use the Enfold Theme with Avia Builder. As stated previously, it works fine on a default theme and seems specific to Enfold. My guess is that whatever changed in 1.17.0 may be using the same hook/filter creating a priority or other conflict with Enfold/Avia Builder and causing the embed code to not display. Issue with Enfold did not exist prior to 1.17.0.
