Same here. I also did make post on that same issue, but it go no reply. Perhaps, yours will be noticed. 

Mine is Android 9.

Just found something else equally interesting: when I try to create Notification alert for known device, an app gives an error every time I try. Screenshot below. Have you tried adding alert for known device?

@Alexandre. thanks for your reply.  I tried enabling notifications for Known Devices and that does work for me.  If I turn on my laptop or turn it off, I get a notification. But this does not work for new devices or for updates. It is a shame that tp-link have not responded to you about this. 

Hi,

Same thing here with iPhone SE (2020) on iOS 14.3.

I set up notifications for unknown devices and have received zero notification, while we are currently updating all our devices to use our brand new DECO MESH wifi...

I was supposed to receive a notification for each new device, isn't it ?

@TP-Link : is it normal ?

Notifications only work if the Deco are in Router mode.

When will the alert for Access Point mode will be available?

I think this is very important!

I run my Deco mesh in Access Point mode. I am getting notification of new devices joining network, in Deco app, in Messages section. I am not getting notifications through Push or email. 

So, notifications for new devices joining network are, indeed, available in Access Point mode. What is not working is alerts on smartphone or by email from TP-Link.

@Alexandre. 

The problem is with the Online / Offline alerts.

@TP-Link 
Hello TP-Link, my Decos are at the latest versions, both firmware and App.
The problem is when the Deco is in Access Point mode.
When the Deco is in Router mode it works ...
