I have had no Mail app notification via Action Centre for more than 3 months. I have tried many suggested solutions (reinstalling via Powershell, changing the settings of Mail and via Settings app) but none of them has worked. Mail app receives e-mails but Action Centre won't inform about it.
The same is with Windows Update. I have had no Windows Update notification since 03.01.2018 via Action Centre. On this day, updates were installed for the last time. Action Centre has not given any notification regarding Windows Update and Windows Update has not searched any updates too. I just searched manually and it found all the updates that Microsoft released during the last 3 months.
So, as I have no notifications from both of these software and I have not received no notifications from Action Centre at all, so I suspect that the problem is not Mail app nor Windows Update, instead Action Centre.
Can anyone come up with a efficient suggestions/solutions?
