You'll need to add your nsec to each client you use. Or, use a browser plugin signer like #nos2x where you enter your nsec into the signer and it authorizes clients to post.

@miljan are you interested in helping me troubleshoot #Primal on Windows desktop? I can no longer post, reply, unfollow. Also, I already have #nos2x and other nsec signers installed and permissions granted. Thanks!

Sure, @Marko from our team will reach out to troubleshoot
