 We continue to listen to your feedback as we iterate on the Cloud Manager. This latest release includes many fixes but one specific customer ask was to add an estimate of your un-invoiced balance to the account display in Cloud Manager. This is an item that was supported in Classic Manager and is now supported in Cloud Manager. You can view your current invoice balance and now your un-invoiced balance to understand what your expenses might be for the month.
