Email (gmail) issues after OS upgrade.
Ok, this is so annoying. It was working just fine and god knows what happened. When read or delete any email messages on my mail app on iPhone, it used to get updated when I log into gmail.com, and now all the messages I have read or deleted, show up as it is when I log into web browser Gmail. how do I fix that when I read or delete any email from my iPhone it should be the same status when I log into Gmail.
