UCP Timeout > Can't Log In Again Without Page Refresh

I keep my UCP page open in a pinned tab in my browser; it only gets closed when I completely close my browser (almost never). It times out after a bit, and requires me to log in again (it seems the timing on this is random, and shorter than what I have in settings, not sure if that is related to this issue or not). When I go to log back in, I enter my username and password, click “Login,” and then it just sits with a greyed out login button, never completing the login. If I hit refresh on the page, and then enter my username and password and hit “Login,” it completes the login as expected. Any thoughts on what is going on here, and if there is a fix? It isn’t a major issue, but it is annoying.
