IP3M-954EB push notification work or not

[tex]

Does push notification work on IP3M-954EB or does it have issues like IP2M-842EB. I started changing out cameras at my house and I like the IP2M-842EB but push notification is so flaky, works when it wants to and Amcrest does not have a fix. Don't mind paying more for IP3M-954EB if push notification works, does anybody use it with no problems or do you have issues. Need to finish upgrading my cameras, few relatives and friends next so please reply otherwise I need to find another vendor even though I like the hardware, software is ? Thanks
