Allow broadcasting to all sites with no access

That’s correct. One has to be a user of the blog in question in order to broadcast there.

There is another solution, though: https://plainviewplugins.com/threewp-broadcast-premium-pack/all-blogs-broadcast-plugin/

Thank you! Just purchased the premium pack and enabled all blogs addon and now we can broadcast.

One question though. We can see “Link this post to its children” option only with users that have access to all sites. Other users can broadcast but can’t add the link to children. Is is possible to enable linking to users that do not have access to all sites?

Have you set the correct permissions / roles in the Broadcast settings, allowing those user roles to link?

It seems that I had set permission for only Authors, now it works! Thanks.
