Issues with signing into Muse Prerelease website

I am a member of the Muse beta community at museprerelease.com. I have been able to log in until about a week ago. Now when I go to museprerelease.com and am redirected to an Adobe sign in page, and enter my credentials, I am directed back to sso.museprerelease.com/signin.html . I can log in to the Adobe website and Muse software, but it is just the beta community that I can not log in to. This is occurring in both Chrome and Safari browsers. I also had the same issue when I tried logging in with another account. I have tried to get help from Adobe chat support, and they directed me to phone support, and then I was directed to a different agent, and then he said to ask about this on the forum. So does anyone have any idea what's going on?
