Hi @tahoeblue08 , for this issue, clearing the cache in a browser and clear browsing history may fix this. Let's confirm first using your browser's private window. Here's how:

• Google Chrome: press Ctrl + Shift + N.
• Mozilla Firefox: press Ctrl + Shift + P.
• Internet Explorer: press Ctrl + Shift + P.
• Safari: press Command + Shift + N

You can also use a different browser since every browser uses a different cache storage folder on your computer. Click this article to see how clear cache. 

You also have a workaround that might work for you. You can click the I forgot my user ID or Password link in the sign in page then reset your password. Comment back. Cheers.
