All these instructions are in the installation manual.
The installer probably has not selected to send the cloud and FM channels at the same time and or changed the events for the users (very unlikely its the latter).
If you log into your cloud online, you can set up the email address for your users, this doesnt appear to affect your FM set on the panel and will give you email notification, it will not give sms notifcations from the cloud itself.
This way in the short term you will get an email for the event, the app should if logged in also get the event directly.
