Email does not cater for all mailboxes in one inbox anymore. How do I get this feature back?

Hi jfromstockholm,

It sounds like you need help with Mail on your iPhone, and I want to help.

If you are viewing your Inbox, tap the account in the top left, then you should be able to select All Inboxes from the list.

Let me know what you're seeing and I'll try to help.

Thanks for using the Apple Support Communities.
