Hi everybody,
I also am having problems not getting push notifications on my Honor 5X from my Arlo (home security camera) app. When the camera senses motion, it sends a notification and records a video. My phone does not receive a push notification, however, when I open the Arlo app I am able to see the video that was recorded.
The funny thing is, I can get immediate push notifications from my Arlo camera on my Motorola Moto X (1st generation) phone.
I have given my Arlo app every notification permission that there is.
I have spent weeks exchanging emails with Arlo tech support, and they have had me try every possible solution in the book, but nothing has worked. It's very discouraging.
UPDATE: I just installed an app called Push Notifications Fixer, and when I walked in front of my Arlo camera, I got an immediate notification! Amazing!
