Not all recent emails are loaded
This is a problem I am finding when using this app on my iPhone 5s, rather than iPad. A limited number of emails are seen. Unread emails do not come up on 'All' sometimes and after opening the most recent emails can not be found, even after repeated refreshing. This is ver annoying and hope it is fixed.
This happens to me, too, on a 5s on iOS 7.1 and a 6 on iOS 8. It's very annoying and makes this app less reliable.
I have this problem too.
