I have a S6 Edge and prior to Marshmallow I was able to choose between thread/conversation view or just all the emails in one long list, the has now gone which is a real pain as my work emails involve huge discussions between a great many people! Does anybody else have this issue? I've googled it and all I get is regarding how to disable this on the Gmail app. My stock email is used for my work email which is a MS Exchange using ActiSync. If anybody uses a different email app that has the thread view, then I would appreciate your thoughts on which email app is best for you.
