I have a strange issue with notifications from Gmail APP. I have already checked that notifications in the application are turned on. Also, I have uninstalled all the updates for Gmail and downloaded them again. The Gmail application is even added to "never put the application to sleep mode". And after these actions, I still don't have any notification that I received a new e-mail. I even changed the notification sound to be sure that it is not the issue with a corrupted sound file or sth like that. Maybe some google service issues? Have any suggestions on what else I should try?
You can close this post. I just find out that "battery saving mode" was the problem here. Checked all issues from the list (link)

Sorry to revive this, but I'm facing this problem ever since I used the battery saver mode for the very first time 4 days back, after using the phone for 6+ months.
I figured out this was the problem, but now I've toggled it multiple times, restarted and everything, but gmail notifications just won't work.
