Client side signature fails to apply and the message 'Failed to acquire auth token' is displayed.
Resolved - Microsoft have confirmed that the original issue impacting customers was the result of a server-side change that has since been reverted.

Our telemetry also confirms that over 40% of customer requests are coming from the newly released version that similarly resolved customer issues prior to Microsoft's deployment reversal, this continues to roll out. We intend to leave this fix in place as it improves the add-ins resilience to possible authentication issues.
