macOS 15.1 beta, no login possible on Safari

Seconding this issue... I ran into it on my iphone onsite when attempting to log into my account as well.  This happens when using Safari on iOS.  I am running iOS 18.0.1 on an iPhone 16 Pro.

I updated my non production macs and iPhone to the latest 18.1 beta and I have no problems.
I think the release of 18.1 is scheduled to next week.
