Why I start roon sever & roon, only show ‘start your subscription’

I hope you fixed your issue. I have tried everything to get Roon to work, spent hours on this, hacking away as an amature. Changed folder to “old,” reloaded Roon, received “there was a problem loading the database” error message, etc. However I cannot even log into my account. Well, I am logging in as I receive the email, “Did you just log into your account?” But my screen just rolls back to the same blank sign in page. When I try finding my Core on this PC when attempting to start the Roon app, it also just keeps looping to "Start your subscription… Are these all the same problem with the latest 880 update? I do not know.
