Sometimes OTX™ pulse data is being downloaded and is generating events, but despite you being subscribed, may clear before the details can be downloaded to events, causing false "You are no longer subscribed to this pulse" alerts. False alarms with the message "OTX Pulse: No information available. You are no longer subscribed to this pulse" may appear as below:
Also note that even if it says no information, if you click through to the details in OTX, you will see the correct pulse that fired.
No workaround available at the time of writing.
