Apps notifications disappearing

[guiduz]

Good evening at all,
I've already tried to do a forum search, but I did not find an answer.
I use Nova Launcher Pro.
I have a problem with notifications. Notifications work in whatsapps and sms, I see them on the top bar.
Instead, in other apps (calendar, inbox by gmail, netatmo security for example) are not seen. They appear quickly on the screen and then disappear.
Can someone help me?
I've already tried to modify the power saving options, but it does not change anything, even by changing the "special access" menu.
Thank you
guiduz

Have you gone into Nova settings and down to Notification badges, tap that and down on the bottom you will see TeslaUnread and enable the apps you want to get notifications from?

Hello, thanks for the answer.
My problem is of not having notification icons in the status bar for applications (for example the notifications of Netatmo, the security camera app ).
I have notification icons only for messaging programs (like whatsapp, sms etc.). For other apps, I have the only notifications that appear on the screen and soon disappear.
Thanks

Please help me!
About phantom vibrations, today I was in front of my pc when I heard a vibration without notification on the phone and I noticed on the PC that I just had an email, so the ghost notification was due to the arrival of the email!

Im having the same issue, I get a vibration, and a quick flash of a notification.
So if my phone is in my pocket, by the time I get it out the notification will be gone.
Text message, whats app and gmail all seem to work

I dont get google voicemail notifications, group me notifications, let go notifications and a few others...help?
