Mail notification on locked screen gone

[Horvath Gyorgy1]

Lumia 640 W10 latest production version
I haven't received mail notifications on my locked screen for weeks now.
The sound notification works fine, only no icon on locked screen.
I did soft reset, it did not help.
I unpinned and re-pinned Outlook Mail, it did not help.
I switched mail notificaion off and on, it did not help.

Same problem here. I believe the last 3 fast ring builds have broken all lock screen notifications running on my L640. It's been such an annoyance (and reported to MSFT), that I happily rolled back to 8.1 yesterday, and probably indefinitely. Having to monitor 2-3 hundred emails a day with my phone, and 8.1 just works better. It's not a grievance, just accepted that W10M is not nearly stable enough for me. The Surface mobile will be nice, but is not a solution in my regard.
