Too much cache buildup in a browser can cause unexpected behavior with the product. You can open your account in a private (incognito) window to clean this up. Utilize these keyboard shortcuts to save time:

• Safari: Command + Shift + N
• Mozilla Firefox: CTRL + Shift + P
• Google Chrome: CTRL + Shift + N
• Microsoft Edge: CTRL + Shift + N

If it works, return to your browsing history and clear its cache. Otherwise, use other supported browsers to help narrow down the cause of this behavior.
