VTO2111d - delayed ring/notification to mobile phone

[Toads]

Hi,

Have my VTO2111d-dwp hardwired to my router via Ethernet.
Port forwarded IP address to my DynDns - so I can receive notifications outside of my home Wifi.

Use 2 mobile phones - Pixel 2 and IPhone 10.

iPhone 10 get the ring notification almost instantly. Around the house (wifi connected) or when I'm not home.
The Google Pixel 2, is delayed ... sometime up to a few minutes!

What is causing this? I doubt its the phone manufactures... it was working great on both phones a while ago.

Thanks!

Is the delay in receiving an email notification? Or a Push notification. They're different. Push is faster....

In the push notification, sometimes works great, and other gets a lot of delay.
Is unstable, maybe is the firmware, but I´m from Argentina, and we havn´t dahua support like others country.
Any help is welcome.
