I updated the pebble and my iPhone 5 has the latest updates. First, I didn't even worry about the "email notifications" set up on the Pebble App. The one where you hit the cloud and can add/delete email accts. Frankly, it didn't do anything for me. Plus, you had to figure out the "host name" and that meant figuring out more than I had time for. This is how I fixed the problem and it has been mentioned above and in less detail. 1. Go to your iphone settings and delete a mail acct. I had three accts listed and just deleted one and reinstalled and was fine for all three accts. Settings>Mail, Contacts, Calendars>chose acct. (mine was hotmail)>delete account. 2. Now you have, or should, add the account back. Settings>Mail, Contacts, Calendars>Add Account (mine was hotmail) 3. You have to make sure the notifications for the NEW account are set up. Settings>notifications>mail>select the newly re-installed account(mine was hotmail)>make sure the notifications is on and it can be viewed in Lock Screen. You will also want to set up the sound and vibration in a manner you like. I have toyed with the phone, watch settings, etc. over and over and this worked. It quits out on you at one point or another but I just reset the one acct and it is working again. Not fun but a easy fix.
