I just ran into the same issue.
When you try and create a new membership, after clicking publish, you get redirected to a thank you page and the membership does not save.
I’m not exactly sire what’s happening but I can see that the plugin is adding a div with an id of major-publishing-actions in the classic editor which is a duplicate of a core wp section.
