A great suggestion from Netmeg in the Features I'd Like to See thread:
I would like to see some notification when there are known issues with an option or tool, so that we don't have to flail around and waste time trying to figure out what's going on.
This type of slowdown today seems like the perfect situation where an update appearing on the log-in screen, or elsewhere, would quell fears of this being an isolated issue and notify users of expected timelines - if any - for resolution.
FYI - I'm unable to access any accounts at present - but I receive this error within my MCC:
Your billing information is temporarily unavailable. At this time, we are unable to provide information regarding your billing information or history on either the Billing Preferences or Billing Summary pages. However, please note that you can still access information unrelated to billing from the menu at the top of any page within your account.
Thank you for your patience. Please check back soon for your updated billing information.
