No notification on Wechat or Google play app updates. topic

Hi pplz,

I'm currently on s.ROM but this problem has occurred in prior tried ROMs too.

I seem to get no notification for wechat incoming msg and even incoming voice or video calls. I only know this because friends have notified me and waiting for a reply via WhatsApp. I then proceed to open Wechat and behold I see multiple msgs waiting and the odd call missed.
I check to see if Wechat is running apps almost every time I reboot and it is with its services running. So what's the problem here?

I also get a similar problem with google play app update notifications... They never appear until I open Google play itself and look in My apps or when I reboot the phone then the notifications I get after the system has loaded.

So is this a problem with the app/gcm services they use? As WhatsApp and telegram runs perfectly.

I Xposed running with boot manager, greenify and amplify, but I have not selected any of these apps to touch the msging or google play apps.

I had the same problem prior to using Xposed FYI.

Any suggestion on what I could do? Or diagnose the problem.

Tks in advance.
