Badging doesn't work well
I have Mail and Boxer side by side on my iPad. Mail updates the app's badge as email comes in. Boxer doesn't. Tried turning background refresh off, which someone said would make Boxer switch to push notifications. Didn't help. This is probably a show stopper for me if I can't get it fixed. Any ideas?

I've got the problem too and I am forced to use other email apps first

I just tested this on my iPhone 5s running iOS9.2.1 with Boxer, Apple Mail and Outlook which doesn't have any problem to show the badge icon when a new e-mail comes in. Boxer was the fastest of the three actually to show '1' as a badge icon.
