Let's say I get a new email in the iPhone Mail App. I open the app, view the message, swipe to delete it and it goes into the trash, out of my inbox. After I do this, the bottom of the app still says "1 Unread." The red notification number on the app itself on the home screen also stays. I always have to close the app, go back in and repeat the process for it to claim the message is deleted.

Also, the message will sometimes stay in the inbox after I swipe it and close the app, like the above, but with no notifications.

Why is this? Is there a known solution to this?
Please note I am not using a VPN and I am using the most recent iOS, Gmail account, on the iPhone 6S.

Thank you for your time.
