I don't receive notifications/calls received on my whatsapp when my phone is ideal/locked for few minutes.
I don't receive notifications/calls received on my whatsapp when my phone is ideal/locked for few minutes. After I unlock the phone, I receive all messages/missed calls messages all at one. Why isn't it working when locked/ideal for sometime? Is it because the APN(Apple Push Notification) settings are not properly configured? Or is it something else. Kindly help. Currently I am facing this issue on my iPhone X XS and 11 Pro.
Because of this issue, I miss many important calls/messages that require immediate attention.
iPhone X, iOS 13
