Not getting whatsapp messages when phone sleeping

[nicholasgibbs]

When I wake phone up all my messages get delivered at once. Also I do not get Whatsapp calls while phone is sleeping. I checked in the app permissions.
Is there some kind of data saver or battery saver on that is causing this?

Yes. Change the power settings for the app as per my screenshot

Thanks. Made the change and will monitor it.
I notice you have Background app management on. Mine was off. Do I need to turn mine on as well? Detect battery draining apps is toggled on for me too.

Not sure I have it on. That setting doesn't seem to affect whatsapp messages coming through.

Hello @nicholasgibbs and @MrAvenger !
I was testing this and I might have found a solution, please try the following.
Settings -> Network & internet -> Data usage -> Mobile data usage -> WhatsApp
In there you will see Unrestricted data usage, try turning it on if it's off and let me know if this solves the issue 🙂
