Hi there @nysci,
Thanks for getting in touch with us! I can help you here ๐
From the screenshots and what you describe I agree with you, this indeed looks like a permissions issue. Is the user an administrator in both sites? DO you have any custom user roles or plugin managing capabilities? Is the site on a multisite network?
Further testing can be downgrading a plugin to a past version and re checking this in the latest working version, or try to re-install last update manually.
Please let me know about it,
Best,
Nico
