Hello @bigbird
Thank you for reaching out to the Community regarding your issue, although I am sorry to hear that you are experiencing issues with your sign in. I wonder if it may think you're not signed in even though you are here. To start off here lets try resigning back in to see if that might correct the issue. I'll leave steps down below.
Once you get a chance to try these steps, please let us know what you find. From there we'll better understand our next steps.
Thanks,
Quicken Francisco
