Google updated iOS version of the Gmail app, which currently offers the option to turn off grouping emails into conversations, which some users were unhappy with. Turning off conversations in the Gmail app settings menu will cause individual emails to appear in your inbox individually, rather than grouped into conversations. You've long had the option to turn off grouping messages into conversations in the desktop version of Gmail. And now you can do so in the Gmail mobile app. However, Google notes that the option to turn off isn't showing up for all users yet, but it should be visible to everyone within the next two weeks.
