Gmail Android app not displaying notifications

[Divine Kataroshie]

Hello ! So, my Gmail App on Adroid (Samsung galaxy S6 with android 7.0) DOesn't display notifications for any of my e-mails at all.

I checked all the notification settings, here are some screenshot : https://photos.app.goo.gl/ENeWmckZNNKkWYpH3

And tried to enable/disable app and remove catche + all data

I'm only getting notifications from other Google apps like Calendar, or Google photos.

Any ideas ?
