Secondly, its been years and you still can't store more than a single email address for a contact. This is so incredibly ridiculous that I have an extremely hard time understanding how they get away with charging what they do.
Lastly, the mobile app drives me nuts. I just can't get used to using it. You delete a message and a notification pop down drops from the top covering the next email so that you can't select it until the pop down notification goes away. This is deal breaking for me as if I have to go through 20 emails I have to sit and wait over and over and over again for this notification to go away. Yes, a message was deleted, I'm the one that deleted it, I don't need a notification telling me I did so. Infuriating to use.
