I have the same issue as Robin and Jordan had, but with version 1.6.9. When I go to General > Notifications I have a lot of options and settings, but there aint any Advanced > Server Badge Counter. Neither can I find server count option in the notification preferences.
For now i have Apple Mail and Airmail side by side to see if there is any new mail. I use Iphone 6 with iOS 10.3.3.
