I prefer the web based version on my laptop. But i use this app to send pics and it will not let me use the web version on my phone now. Biggest issues...I DONT SEE ALL MY MAIL. Ive searched for specific emails and they do no exist in the app... But they are on the web version. I would be 100% screwed if I had to rely only on this app for mail. Ha I wouldn't it would be irresponsible of me to soley rely on this app. 10-20% of my emails disappear into thin air. Its crazy.
