I'm using a theme today (the default one) on my 9700. I have several e-mail accounts but I chose to have only one showing in the Inbox (Options> Inbox Settings> unchecked the accounts i didn't want). It works perfect.
Since my latest OS upgrade (.680) the mails I'm receiving on any account show up on the main screen. Even the ones I unchecked. They don't appear in the Inbox, only on the main screen. It's very embarassing. I want them appearing nowhere, only in the account icon.
How to get rid of it ? Don't really want to downgrade...
Try switching from the Today to the icon's theme provided on your device, reboot it (turn it off, battery pull) and see if that changes anything after you switch it to the Today section of the theme.
