I use the Unified Inbox feature and generally keep the Unread filter on unless I'm looking or searching for a specific message. Opening the app or reloading the Inbox takes up to 15-sec to go from a blank screen to showing the messages. I do have all the inboxes indexed on the device but the issue was observed with the standard 25 message limit as well. I have not had similar delays or have been met with a blank screen every time an email app is opened. Is there an ability to speed up the initial and subsequent loading times? It does hamper workflows and skews the perception of the app towards being inefficient or otherwise less than capable compared to similar apps.
