From above, I can confirm that alarm notifications were generated and sent to 12 recipients in total, including recipients identified as push notifications to your iPad Pro, iPhone, and the SMS number tied to your primary user name. Those were all sent for that event.
Your primary email is not set up as a recipient for alarm notifications. You can edit this under the Notifications page, then select the Alarm notification.
If you believe you are having an issue receiving notifications on your devices, the first thing to try is to place the account on test mode in the System Manager here and then test by triggering an alarm.
Which devices do not receive alerts? Is it the same ones or do you receive them in the test?
Did you replace your phone with a new model?
Also, I thought that if someone disarms a tripped alarm? dispatch cancels everything?
That would occur in normal circumstances. You have special instructions on your account requesting that no contact be made prior to dispatch. This affects the standard process (this is also the cause of the delay, it looks like in this instance the operator reached out to their monitoring station management to confirm the correct process given your special instruction.)
