Hello,
I have a similar problem, or rather 2, to be precise:
1) For blog posts imported from a former domain into out new, the plugin retrieves the old url (which in many cases doesn’t exist anymore)
2) For newly created blogs in the network, all displayed post links have the format blogs.ourdomain.com/?p=123. By clicking on them, the blog opens after apparently redirecting to the correct permalink (blogs.ourdomain.com/post-name). The permalink setting for these new blog is explicitly set to https://blogs.ourdomain.com/blogname/sample-post/
Any thoughts what might be wrong? Could need your help desperately.
Thanks so much & all the best,
Martin
