I am not sure if this is an App, android configuration or Samsung Z fold 5 issues. I am not getting instant notifications from some of the apps on the phone.  I use some of the apps to notify me of available jobs, but by the time the notification comes to alert me, the jobs are already gone. For  example the notification may come in the email and and the App alert, however,  I get no  notifications from Google Gmail app unless I open the phone. I get delayed notification from apps. 

I have the iPad and I can see the email notification on the iPad, but at the same time there are no Email notifications on the phone. Strangely, the alerts from ESPN occur at the same time both on the iPad and the phone.

I checked the alert setting for the gmail and the app I used to notify me about the jobs and made sure that both of them are not sleeping and battery set to Unrestricted. I am not sure if there is any other settings.
