ThingSpeak Account Message Usage cannot be accessed

Recently my the tab to access ThingSpeak Account usage data and graphs is no longer displayed when I login.

My data is still being uploaded to my channels and is displayed.

Why can't i access my ThingSpeak message usage data?

Can you try accessing the page in an incognito or private browser window?

Using private browser mode in Firefox my login tab now appears and i can access my account.

I will clear cookies which is often the cause of this type of issue. Thanks
