ios 7 on iphone 4s mailboxes not showing for gmail
Hi all, I have an iphone 4s with ios 7 with my gmail account synced. When I look in 'Mailboxes', it lists Inbox, VIP and then under 'Mailboxes' it shows Drafts, Sent, Junk etc. and then a few of my gmail folders 'Friends, Work-Related etc. etc. ' in alphabetical order, but not all of them.
Any advice on why only some of my folders (mailboxes) are showing, and others aren't? Or how to add my mailboxes (folders)?
I've tried restarting my phone, and also deleting and re-adding my gmail account but to no avail...
iPhone 4S, iOS 7
