Yesterday, I got the Samsung A14 for my Dad and it was working quite smoothly. Today, out of the blue, it stopped receiving any WhatsApp notifications - be it messages or calls - while it is locked. It shows to the sender that the phone isn't connected to the internet (i.e., one tick for messages and calling status for calls). I have literally tried everything from making sure the notification settings are the way they're used to, the lock screen settings are at default, and all the WhatsApp notifications settings are turned on - but nothing has worked.
Dunno if this helps but I tried contacting WhatsApp and they informed me that the A14 uses Google Cloud Messaging (GCM) to receive push notifications in WhatsApp. Then I got ghosted by them with no clue of what to do if their instructions (which I highlighted above) don't fix the problem. After some research, turns out GCM got deprecated in 2019 and some Fire Cloud thingy replaced the old system.
Has anyone found a fix/encountered the same problem?
Thanks in advance for all the help.
