Hi Katrine,
Thank you for the reply and the details.

If you put a link directly in activity content, that is handled by BuddyPress not MediaPress. BuddyPress supports oembed links out of the box for all the providers supported by WordPress.
https://developer.wordpress.org/reference/hooks/oembed_providers/

In case of MediaPress, we do not support embedding, we support attaching oembed media to activity or a gallery. We also limit to the providers which return ‘photo’ or ‘video’ as type in the oembed response. That helps us to identify what type of content we are dealing with.

The Activity Link preview works with both the oembed and non oembed urls. For non oembed, they scrap the page and parse it to extract media/title etc.

I believe I know the reason for our conflict with activity preview as I had a look at their code today. I will post an update in next 24-48 hours.

Hi Katrine,
Thank you for reporting the issue.

I am sorry, I don’t see any issue that it will cause with 3rd party code unless they are doing something strange. BuddyPress global search is abandoned(also unlisted from WPorg due to security issue)
https://wordpress.org/plugins/buddypress-global-search/

I am not sure which direction I should point you to. I will suggest if feasible, try using a different plugin.

Hi Katrine,
Thank you for using the plugin.

Please give it a try.

add_filter( 'bp_lock_unlock_user_can_update_activity', function ( $can ) {
	return is_super_admin();
} );

Thank you. I am looking forward to it.
