I tried out a bunch of different email apps yesterday. Most had the same issues as Edison Mail which sucks cause thats my "goto" email client. Gmail works, but I'm not a fan of the interface. Outlook works as that is what I use for my company emails through Exchange, but since it doesn't offer color coding, I don't like mixing my other email accounts with it. Spark was hit or miss, sometimes it would show up with the badge counter, but never on the lock screen. Airmail is a complete waste now that it went subscription base, but, it still did not show the badge counter nor the lock screen notifications. Newton had issues, and is not updated frequently enough. The built in email client experience intermittent notification issues, and would not download new email without opening the app first? How stupid is that!
Right now, even though I'm not a fan of the interface, PolyMail is working on all accounts. Badges show up properly. Notifications show up properly, and email arrives almost instantaneous. Notifications on my watch work perfectly again.
Pretty sad that we are having these major issues on the 1 area that 99% depend on everyday.
What doesn't make sense though is my old XS did not experience any of these issues throughout the beta program? Edison Mail worked like a champ until I switched to my 11 Pro.
