I use iPad and iPad Email client has same issue. In IMAP Gmail Accounts when we go on say Send Email it refreshes folders and starts to fetch headers and then emails. Is it not possible to refresh all folders periodically with full email content so that we can quickly view and deal with emails. Often on slower networks, there is time wasted as first if we click Sent Mail folder it fetches mail headers and then fetches emails. If we click on email, we have to wait till it fetches email. Same issue I faced in iPad default email client.
Thanks for the suggestion! At the moment, we have no way to do this that wouldn’t slow down the app significantly. We will likely explore different ways to do this later on, but have no immediate plans to work on this. Thanks for your active interest, and please keep the suggestions coming!
