Redirect Issue (User Already Logged in?

Having the same issue as this thread: https://www.ads-software.com/support/topic/redirect-if-already-logged-in-4/

Happened once when a user was on one device, but then switched to another. Not sure if it is because the user is already “logged in” on their first device.

I also use a security plugin that changes the admin backend login URL, but I feel like that shouldn’t matter as others have not reported an issue.

As the other thread mentioned, there may be an issue with the system thinking someone is already logged in or something as we also have had people somehow make it to the WP Dashboard, exact situation as above.
