Since some weeks almost every 5th Email I am sending fails. And the worst part: the app almost does not tell you when that happens. There is only a tiny message showing whether sending has worked or not. I often do not even wait for that message and just move on doing other things, so I don't see the message, as I expect sending email to just work. Even more frustrating when the email isn't even saved in drafts, so I have to do everything all over again. Please consider adding pushes for this

Ok on the whole, but often won't download new emails & also won't delete emails...by that I mean that you can swipe left to delete, but it reappears, so app needs deleting & reinstalling to fix. Also when deleting large amounts of emails (if you get lots if emails from a certain sender eg wowcher so searched for all from them), if you select 'select all', it only selects what's visible on the screen as opposed to all the emails so deleting all emails from a particular sender can take a while.

It used to be great but no longer displays notifications for new emails. I have gone through all the app settings and my phone settings multiple times to make sure that notifications are turned on, but I'm still not notified about new emails. I can only see new emails by opening the app and refreshing it.
