The plugin doesn’t work in multisite

A plugin with a good UX.

But it doesn’t work for multisite, I activated for one of the sites and the plugin created a page and configuration options on all sites.
At this moment, I could not access the other sites, I could only access the admin where the plugin was active.

Another problem, when I deactivated the plugin, the redirection from login to loginpress was still working, so at this time I could not access the admin of any site.
