May I ask if you are still experiencing this issue? Is this issue replicable on incognito or a different browser?
I don’t see any issue on the Cloudflare Status Page in past days, however could be due to some changes in the API.
I’d suggest you to try clearing your Web browser cache and cookies and login back again.
Otherwise, try using a different Web browser, or an Incognito mode (Private window), or even different network type like e.g. mobile data.
If you are still having this issue, could you please:
