App Connections management trouble

Use the new Blink iot app. I can’t figure out how to track the fact of entering / exiting the application by the device. BLYNK_APP_CONNECTED function does not work. In the old application, it was necessary to enable notification data in the settings, but in the new application I did not find such an opportunity.

It’s no longer supported.

Are there other ways to react to the device when the user logs into the application?

No. Could you please tell us your use case?

In the application being developed, there is no need to send data constantly. And I would like to be able to send data only during the period of using the application.
Internet at the place of application of the device from the gsm modem. esp is connected to the modem via wifi. esp uses a built-in camera to photograph an object so that the user can remotely control the execution of commands

I see. We removed it as it was a rarely used feature. Maybe we’ll return it at some point.
