I've downloaded the BT Mobile App for an Android phone.
The app gives the option to add additional e-mail accounts. I've added a second account and can view and send, but I only get notified about new e-mails for the first e-mail account I set up on the App.
I think I've looked 'everywhere' but can't see any settings for notifications on individual e-mail accounts. Have I missed something or is the limited notification option just a feature of the App?
Delete the app and install a proper email app such as Blue Mail or Aqua Mail.
