Ok so I have notice several times on my iPhone. The other day I had an email that I did not delete, but just read and left in my inbox. I went back to look for the email, and it was gone. I opened the gmail app and it was still in my inbox on that app. What the heck happened in the mail app? Also I have an exchange work email on my iPhone that is only showing 2 emails in the inbox when I have over 20. What is it doing with my emails?
