Newsletter Options Missing from Post Editor

I am an NG Pro user, and am in the block editor, writing a post.

Always before, there was a box to check to send a post as a newsletter. And, at the bottom, below the post editor, there was a section for settings for the newsletter.

Now there is none of that.

According to the Plugins page, I am using Newsletter Glue Pro Version 1.4.1.2.

In the sidebar, there is a section that shows “Newsletters (beta)” and I wonder if this is the problem: maybe there is a bug in the beta?

I guess I can’t post my post until I figure this out, because I don’t know if it will go out as a newsletter. And, if it will, I have no way to preview it by sending myself a test.

Please help?
