When the screen is locked, it seems like WhatsApp is not being connected. I'm not able to receive the notification thought I'm getting notifications from Gmail.Is it a known issue? When it will be fixed..
Also my wearables(Nokia steel hr) is not being connected to the phone when screen is locked..
Hi! To fix this go to: Settings - Battery - Background Activity Manager, then on the list find your app then check both box labeled (Auto Activate and Lockscreen). Once it is checked open your app then you should be good to go.
