Hi @TanyaNewman,
In cases where the dashboard doesn't load or is flashing, I've found that the most common causes are either an outdated browser (Chrome, Firefox, Edge, etc) or operating system (Windows, macOS, Android, etc). I'd first suggest making sure your device and browser are both updated. If that doesn't work, I'd next suggest clearing your browser cache and cookies. If that still fails, you could try a different browser than the one you normally use. I'm hopeful one of those suggestions will work!
