Additional report here: 7229622-zd-a8c

Disabling "show inline embed" is a workaround.

This was fixed at the Core level with https://github.com/WordPress/gutenberg/pull/55667

📌 ACTIONS

• Retested today by checking https://wordpress.com/support/embed-a-pdf-file/ in Safari, and it's now working as expected!
• Closing as resolved.

User reporting a newish instance of this on a Simple site: 7304933-zd-a8c

I am able to reproduce on a Simple site with comments enabled on the post/page that has the embedded PDF and seems partially related to this bug: https://github.com/Automattic/wp-calypso/issues/84132

It appears to potentially be affecting the 20% of Simple sites using Verbum p7DVsv-j4Q-p2, which this site is. It also works on my test site when unproxied, since Verbum only loads when proxied. Is there a way to disable Verbum on this site to determine if it's the cause or not?

Another report of this issue in 8183827-zd-a8c on a simple site. Able to replicate on a test simple site as well.

Another report here 8224188-zd-a8c on a simple site.

I created a test site and tested across several free themes and found the same issue to persist consistently across them all. In fact, I could not get PDF inline embed to work on any theme I tried. I experienced the same result on both Safari and Chrome web browsers.
