Gmail loads very slowly on stock iPhone mail app
Recently (probably the last 2 weeks or so), I have noticed my gmail account using the stock mail app retrieving the emails very slowly. First, it will load where the mail comes from and the subject, but the body of the mail comes in very very slowly, even if I click into that message, the body of the message just shows "LOADING" and never loads the message.
And when I delete an email from the iPhone mail app, it doesn't reflect it on gmail via web browser for a long time.
Has anyone experienced this and any solutions?
Thanks
iPhone 8, iOS 11.2.6
