Maintenance/Coming soon page doesn’t stop members logging in

This is unrelated to my previous issue so I posted a new topic.

I’m wondering why my member login page is accessible to users even when my site is set to coming soon or maintenance mode. None of the other pages are open except the front end member login page and it is allowing subscribers to sign in and use the website as if it were live (even when it should be in maintenance mode). Would appreciate it if you could share some advice on this matter.

Thanks again
