Hi, I need some help with my APPLLP 4 Pro. I cannot for the life of me get live notifications from my Google Voice app. I’ve turned on unrestricted data usage and turned off battery optimization. I don’t have battery saver on, and yet I STILL don’t get my notifications from it? Any ideas or help would be appreciated, thank you

It seems I had forgotten the first step in “optimization, clean task, app list”. So silly of me! Thank you so much for pointing me to this article, I had searched in the forum but nothing was popping up. Works like a charm now, take care!

Exactly right @vladimir_lutzu
Thanks.
If that doesn’t work I would be very surprised because there would be hundreds of people who have the problem.
To easily update play services, go to Settings / apps / play services and scroll down to advanced settings for the app.
Tap on the line which says “installed from play store”. This will take you to the play store update for play services (which is usually hidden).
Then update it.
Follow up with play store update by going to the settings menu in the play store app and click on the version number.
Cheers
It’s usually play services and webview that need updating 
Problem solved…
Just go to playstore
Settings
Update playstore
Done

I have checked with Maria and she said 1.6 will be released this week, since I am on 1.5, I will check these claims before updating to see if it is software related.
If you upgrade to v1.6, you can not downgrade back to v1.5.
As long as you understand this, no worries.
The pixart BT + sensor chip cannot go back from v1.6.
Up until v1.6, you can flash up and down versions.
When you flash back from v1.6 you will be fine until the Pix chip firmware. This is where it fails.
Just so you know

Isn’t it possible to flash Pixart via WiiteDFU? Also wondering if the OTA they are going to release has other changes except the sleep algorithm, if not I can upgrade now.
Has anyone managed to use the build-in heart rate sensor with a third party fitness tracker app?
Yes it is. Usually.
But from v1.6 you can’t download the Pix chip firmware because there is a “no downgrade flag” set on the chip.
Well that’s not good. Wondering the reason behind it. It is Saturday now and still no OTA, I don’t understand why is Maria giving false ETAs.
It’s simply because the latest batch of production Z40 has a slightly different Pixart chip.
So it cannot use previous versions of firmware.
Don’t worry, it’s not a conspiracy or anything nefarious 
I suspect that the eta is elastic because they have already sent a few samples to you and they are also likely waiting for the factory.
Don’t be concerned.
Oh what’s the difference if not a secret? Wondering since mine has 1.5 preinstalled whether it is the new one the old one.
After not using it for a month my watch displays a blue battery with an exclamation mark when trying to charge it.
I left it to charge for several hours but the display did not change and the watch did not charge. It also doesn’t boot when long pressing the buttons.
Any ideas whato to do?

Return it or disconnect the battery.
If you have access to a photo repair service, I would ask them because it is quite tricky.
Avoiding damage is tricky.
If you disconnect, it will reset the “memory” of the watch - battery relationship.
This sometimes happens after long periods of not using the watch at all.
