Investigating
We are currently looking into issues related to customers who are unable to download system assets (i.e. seeing distorted screens or missing icons) due to upstream CDN 503 errors. In the mean time, if you have a VPN, setting your location to somewhere outside of the Southeast may temporarily resolve this issue.
