I have the same issue.
All the smart events are logged and viewable on the DVR but the push notifications dont happen now to my iphone and ipad.
The was professionally installed along with my alarm too (so they run off the same app Procontrol +)
I get voice notifications when my alarm is set and there is a log in the "alarm panel" side of notifications ... but noting in the Procontrol tab??
I have had them back but they said there is no reason is shouldn't be working???
I have checked every setting I can think of but nothing - all my devices are less than 1 year old and up to date???
Thanks
Dan
